* cloudstack: remove choice list for hypervisor param

* cloudstack: remove E326
* add changelog fragment
* Add win_hosts module
added win_hosts module for easier manipulation of hosts entries in "%windir%\system32\drivers\etc\hosts" for windows systems
* Update win_hosts.py
* Add alias support to win_hosts module (#1)
* win_hosts supports aliases
added support for adding / removing aliases from a host entry, rather than adding a new entry
added ability for win_hosts to detect aliases:
`192.168.1.1 alias1 alias2 alias3`
```
win_hosts:
host_name: alias2
ip_address: 192.168.1.1
```
will result in `192.168.1.1 alias1 alias3`
also includes `replace` and `add` as options for `ip_action` (`replace` is default)
for example:
```
192.168.1.1 my_reused_alias
192.168.1.2 my_reused_alias
```
with
```
win_hosts:
host_name: my_reused_alias
ip_address: 192.168.1.3
ip_action: add
```
the result will be
```
192.168.1.1 my_reused_alias
192.168.1.2 my_reused_alias
```
but with `ip_action=replace` the result would be
```
192.168.1.3 my_reused_alias
```

It was obvious that (because of an incorrect example) people were using
the **xml** module incorrectly, specifying the `attribute` parameter
where it was not supported (i.e. ignored).
While this functionality would have been useful, it currently returns as
if the information was requested from the parent, so we cannot simply
make it to what would be expected.
Therefor the real solution is to provide a warning when we find
incorrect use, and deprecate this use. Then later we could implement
this functionality correctly.
While troubleshooting this issue, I found that in some cases our
integration tests were not being run when we expected it.
This fixes#53459

When creating an ElastiCache redis cluster/instance via this module using a list of security group names (i.e. "FooSG") with `security_group_ids`, the module will fail to create the redis cluster/instance.
When using the security group ID (i.e. "sg-XXXXXXXX"), the cluster is created successfully. Tested with Ansible v2.7.8.

Currently, if we try to stop or start a network two time in a row, the
second call will fail. With this patch:
- we don't recreate a network, if it exists
- we only stop a network if it's active, and so we avoid an exception
saying the network is not active

* nxos_interfaces_ospf: fix passive-interface states & check_mode
This fix addresses issues #41704 and #45343.
The crux of the problem is that `passive-interface` should have been treated as a tri-state value instead of a boolean.
The `no` form of the command disables the passive state on an interface (allows it to form adjacencies and send routing updates). It's essentially an override for `passive-interface default` which enables passive state on all OSPF interfaces.\*
This `no` config will be present in `running-config`.
\**See `router ospf` configuration.*
Since both enable and disable states are explicit configs, the proper way to remove either of these is with the `default` syntax.
Passive-interface config syntax:
```
ip ospf passive-interface # enable (nvgens)
no ip ospf passive-interface # disable (nvgens)
default ip ospf passive-interface # default (removes config, does not nvgen)
```
Code changes:
* `passive_interface` param changed from boolean to string, restricted to `true`,`false`,`default`.
* Several passive-interface specific checks were added because the existing module logic tends to test for true or false and doesn't handle the None case.
* Fixed `check_mode`.
Sanity verified on: N9K,N7K,N3K,N6K
* Fix doc header
* Unit tests for passive-interface
* doc fix#2
* Fix indent for SA
* Remove 'default' keyword, restore bool behavior
* remove changes to sanity

When using before and after in combination, the opposite behavior was induced. This PR makes the the replacement happen between the specified patterns as intended.
* Added integration tests
* Add changelog, porting guide entry, and minor doc fixes
* Removed required_together, updated tests
Since required_together: privatekey_path -> friendly_name, is not always
required it has been removed.
Updated openssl_pkcs12 integration tests to be in line with other
openssl_* modules, and added a test for export with no privatekey_path.
* linter fixes
* Removed cryptography from tests
* Added changelog fragment
* Removed non-necessary select_crypto_backend
This avoids holding open _new_stdin within the parent process, where
subsequent WorkerProcess forks will duplicate it, producing significant
noise in the FD table of every worker.
Fix by overriding start() and moving the work to there, with a finally:
to ensure parent FD is closed after start().
* Fix bug in data returns for some queries used by facts module
* Add additional query to return all servers (up to 5000)
* Fix key checking in rest_api
* Not all Backings are equal

* search for: `ip route 192.168.20.64/24 192.0.2.3`
