crypto: deprecate native Hashicorp Vault support (#11352)
This commit deprecates the native Hashicorp Vault
support and removes the legacy Vault documentation.

The native Hashicorp Vault documentation is marked as
outdated and deprecated for over a year now. We give
another 6 months before we start removing Hashicorp Vault
support and show a deprecation warning when a MinIO server
starts with a native Vault configuration.

validate storage class across pools when setting config (#11320)
```
mc admin config set alias/ storage_class standard=EC:3
```

should only succeed if parity ratio is valid for all
server pools, if not we should fail proactively.

This PR also needs to bring other changes now that
we need to cater for variadic drive counts per pool.

Bonus fixes also various bugs reproduced with

- GetObjectWithPartNumber()
- CopyObjectPartWithOffsets()
- CopyObjectWithMetadata()
- PutObjectPart,PutObject with truncated streams

fix: refactor locks to apply them uniquely per node (#11052)
This refactor is done for few reasons below

- to avoid deadlocks in scenarios when number
  of nodes are smaller < actual erasure stripe
  count where in N participating local lockers
  can lead to deadlocks across systems.

- avoids expiry routines to run 1000 of separate
  network operations and routes per disk where
  as each of them are still accessing one single
  local entity.

- it is ideal to have since globalLockServer
  per instance.

- In a 32node deployment however, each server
  group is still concentrated towards the
  same set of lockers that partipicate during
  the write/read phase, unlike previous minio/dsync
  implementation - this potentially avoids send
  32 requests instead we will still send at max
  requests of unique nodes participating in a
  write/read phase.

- reduces overall chattiness on smaller setups.

ListObjects Metadata Caching (#10648)
Design: https://gist.github.com/klauspost/025c09b48ed4a1293c917cecfabdf21c

Gist of improvements:

* Cross-server caching and listing will use the same data across servers and requests.
* Lists can be arbitrarily resumed at a constant speed.
* Metadata for all files scanned is stored for streaming retrieval.
* The existing bloom filters controlled by the crawler is used for validating caches.
* Concurrent requests for the same data (or parts of it) will not spawn additional walkers.
* Listing a subdirectory of an existing recursive cache will use the cache.
* All listing operations are fully streamable so the number of objects in a bucket no 
  longer dictates the amount of memory.
* Listings can be handled by any server within the cluster.
* Caches are cleaned up when out of date or superseded by a more recent one.

remove safeMode behavior in startup (#10645)
In almost all scenarios MinIO now is
mostly ready for all sub-systems
independently, safe-mode is not useful
anymore and do not serve its original
intended purpose.

allow server to be fully functional
even with config partially configured,
this is to cater for availability of actual
I/O v/s manually fixing the server.

In k8s like environments it will never make
sense to take pod into safe-mode state,
because there is no real access to perform
any remote operation on them.

certs: refactor cert manager to support multiple certificates (#10207)
This commit refactors the certificate management implementation
in the `certs` package such that multiple certificates can be
specified at the same time. Therefore, the following layout of
the `certs/` directory is expected:
```
certs/
 │
 ├─ public.crt
 ├─ private.key
 ├─ CAs/          // CAs directory is ignored
 │   │
 │    ...
 │
 ├─ example.com/
 │   │
 │   ├─ public.crt
 │   └─ private.key
 └─ foobar.org/
     │
     ├─ public.crt
     └─ private.key
   ...
```

However, directory names like `example.com` are just for human
readability/organization and don't have any meaning w.r.t whether
a particular certificate is served or not. This decision is made based
on the SNI sent by the client and the SAN of the certificate.

***

The `Manager` will pick a certificate based on the client trying
to establish a TLS connection. In particular, it looks at the client
hello (i.e. SNI) to determine which host the client tries to access.
If the manager can find a certificate that matches the SNI it
returns this certificate to the client.

However, the client may choose to not send an SNI or tries to access
a server directly via IP (`https://<ip>:<port>`). In this case, we
cannot use the SNI to determine which certificate to serve. However,
we also should not pick "the first" certificate that would be accepted
by the client (based on crypto. parameters - like a signature algorithm)
because it may be an internal certificate that contains internal hostnames. 
We would disclose internal infrastructure details doing so.

Therefore, the `Manager` returns the "default" certificate when the
client does not specify an SNI. The default certificate the top-level
`public.crt` - i.e. `certs/public.crt`.

This approach has some consequences:
 - It's the operator's responsibility to ensure that the top-level
   `public.crt` does not disclose any information (i.e. hostnames)
   that are not publicly visible. However, this was the case in the
   past already.
 - Any other `public.crt` - except for the top-level one - must not
   contain any IP SAN. The reason for this restriction is that the
   Manager cannot match a SNI to an IP b/c the SNI is the server host
   name. The entire purpose of SNI is to indicate which host the client
   tries to connect to when multiple hosts run on the same IP. So, a
   client will not set the SNI to an IP.
   If we would allow IP SANs in a lower-level `public.crt` a user would
   expect that it is possible to connect to MinIO directly via IP address
   and that the MinIO server would pick "the right" certificate. However,
   the MinIO server cannot determine which certificate to serve, and
   therefore always picks the "default" one. This may lead to all sorts
   of confusing errors like:
   "It works if I use `https:instance.minio.local` but not when I use
   `https://10.0.2.1`.

These consequences/limitations should be pointed out / explained in our
docs in an appropriate way. However, the support for multiple
certificates should not have any impact on how deployment with a single
certificate function today.

getDisksInfo: Attribute failed disks to correct endpoint (#10360)
If DiskInfo calls failed the information returned was used anyway 
resulting in no endpoint being set.

This would make the drive be attributed to the local system since

Instead, if the call fails record the endpoint and the error only.

admin: new API for creating KMS master keys (#9982)
This commit adds a new admin API for creating master keys.
An admin client can send a POST request to:
```
/minio/admin/v3/kms/key/create?key-id=<keyID>
```

The name / ID of the new key is specified as request
query parameter `key-id=<ID>`.

Creating new master keys requires KES - it does not work with
the native Vault KMS (deprecated) nor with a static master key
(deprecated).

Further, this commit removes the `UpdateKey` method from the `KMS`
interface. This method is not needed and not used anymore.

Reroute requests based token heal/listing (#9939)
When manual healing is triggered, one node in a cluster will 
become the authority to heal. mc regularly sends new requests 
to fetch the status of the ongoing healing process, but a load

doing the healing request.

This PR will redirect a request to the node based on the node 
index found described as part of the client token. A similar
technique is also used to proxy ListObjectsV2 requests
by encoding this information in continuation-token
