MultiError: Refactored MultiError for more concise and safe usage. (#8066) 
* MultiError: Refactored MultiError for more concise and safe usage.

* Less lines
* Goland IDE was marking every usage of old MultiError "potential nil" error
* It was easy to forgot using Err() when error was returned, now it's safely assured on compile time.

NOTE: Potentially I would rename package to merrors. (: In different PR.

Gracefully handle unknown WAL record types. (#8004) 
As we're looking to expand what's in the WAL,
having old Prometheus servers ignore the new record types
rather than treating them as corruption allows for better
upgrade/downgrade paths.

Adjust some tests accordingly, so they're still testing what they're
meant to test.

Chore: Log segment number when segment read failed (#7687) 
* Chore: Log segment number when segment read failed

To manually fix the WAL files, it is good to know where the corrupt
happened so we should log the segment number when the read failed.

Fix bug with WAL watcher and Live Reader metrics usage. (#6998) 
* Fix bug with WAL watcher and Live Reader metrics usage.

Calling NewXMetrics when creating a Watcher or LiveReader results in a
registration error, which we're ignoring, and as a result other than the
first Watcher/Reader created, we had no metrics for either. So we would
only have metrics like Watcher Records Read for the first remote write
config in a users config file.

Garbage collect asynchronously in the WAL Watcher 
The WAL Watcher replays a checkpoint after it is created in order to
garbage collect series that no longer exist in the WAL. Currently the
garbage collection process is done serially with reading from the tip of
the WAL which can cause large delays in writing samples to remote
storage just after compaction occurs.

This also fixes a memory leak where dropped series are not cleaned up as
part of the SeriesReset process.
