While it's useful to keep track of the different versions (Ruby, GitLab,
etc) doing so for every point wastes disk space and possibly also RAM
(which InfluxDB is all to eager to gobble up). If we want to see the
performance differences between different GitLab versions simply looking
at the performance since the last release date should suffice.

Not really needed, but having code that is not used around is confusing, so lets
remove it

Fix project transfer e-mail sending incorrect paths in e-mail notification

The introduction of ActiveJob and `deliver_now` in 7f214cee caused a race
condition where the mailer would be invoked before the project was committed
to the database, causing the transfer e-mail notification to show the old
path instead of the new one.

This removes the need for Sidekiq and any overhead/problems introduced
by TCP. There are a few things to take into account:

1. When writing data to InfluxDB you may still get an error if the
   server becomes unavailable during the write. Because of this we're
   catching all exceptions and just ignore them (for now).
2. Writing via UDP apparently requires the timestamp to be in
   nanoseconds. Without this data either isn't written properly.
3. Due to the restrictions on UDP buffer sizes we're writing metrics one
   by one, instead of writing all of them at once.

Newlines aren't really needed and they may mess with InfluxDB's line
protocol.

Downcased user or email search for avatar_icon.

GitLab users are defined with their mail address which is enforced to be lower case. When a commit is listed in the history whose committer mail address is not written in all lower case, the corresponding GitLab user won't be found because the search is case sensitive resp. the mail address to search for not downcased.

This is a temporary hotfix that allows to access build artifacts created
before 8.3. See #5257.

This needs to be changed after migrating CI build files.

Note that `ArtifactUploader` uses `artifacts_path` to create a storage
directory before and after parsisting `Ci::Build` instance, before and
after moving a file to store (save and fetch a file).
