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.
