- Currently for the `nosql` module (which simply said provides a manager
for redis clients) returns the
[`redis.UniversalClient`](https://pkg.go.dev/github.com/redis/go-redis/v9#UniversalClient)
interface. The interfaces exposes all available commands.
- In generalm, dead code elimination should be able to take care of not
generating the machine code for methods that aren't being used. However
in this specific case, dead code elimination either is disabled or gives
up on trying because of exhaustive call stack the client by
`GetRedisClient` is used.
- Help the Go compiler by explicitly specifying which methods we use.
This reduces the binary size by ~400KB (397312 bytes). As Go no longer
generate machine code for commands that aren't being used.
- There's a **CAVEAT** with this, if a developer wants to use a new
method that isn't specified, they will have to know about this
hack (by following the definition of existing Redis methods) and add the
method definition from the Redis library to the `RedisClient` interface.
Change all license headers to comply with REUSE specification.

Continues on from #19202.
Following the addition of pprof labels we can now more easily understand the relationship between a goroutine and the requests that spawn them.
This PR takes advantage of the labels and adds a few others, then provides a mechanism for the monitoring page to query the pprof goroutine profile.
The binary profile that results from this profile is immediately piped in to the google library for parsing this and then stack traces are formed for the goroutines.
If the goroutine is within a context or has been created from a goroutine within a process context it will acquire the process description labels for that process.
The goroutines are mapped with there associate pids and any that do not have an associated pid are placed in a group at the bottom as unbound.
In this way we should be able to more easily examine goroutines that have been stuck.
A manager command `gitea manager processes` is also provided that can export the processes (with or without stacktraces) to the command line.

Gitea was not able to supply any authentication parameters to it. So this brings support to do that, along with some light extraction of a couple of bits into some separate functions for easier testing.
I looked at other libraries supporting similar RedisUri-style connection strings (e.g. Lettuce), but it looks like this type of configuration is beyond what would typically be done in a connection string. Since gitea doesn't have configuration options for manually specifying all this redis connection detail, I went ahead and just chose straightforward names for these new parameters.
There is a bug setting the redis db in the common nosql manager whereby the db path
always fails.
This PR fixes this.

* Allow common redis and leveldb connections
Prevents multiple reopening of redis and leveldb connections to the same
place by sharing connections.
Further allows for more configurable redis connection type using the
redisURI and a leveldbURI scheme.
