* Also addressed feedback from https://gitlab.com/gitlab-org/gitlab-ee/commit/fcbfe56207f64da07deb7f3a8cbdcd505069edbd

* Now #url= and #url always handle the full URL, encryption is done transparently
* #safe_url was added for future purposes
* Little refactor for UpdateRemoteMirrorService

* Also added small fix for the scenario when the remote repo is empty
 and does not have tags.

* Add the ability to skip tags when fetching a remote repo.

Use more accurate timestamps for InfluxDB.

See merge request !3617

This allows us to track how much time of a transaction is spent in
dealing with cached data.

Use gitlab-workhorse 0.7.2

See merge request !3570

This is the inverse of 51894dbb.

This changes the timestamp of metrics to be more accurate/unique by
using Time#to_f combined with a small random jitter value. This
combination hopefully reduces the amount of collisions, though there's
no way to fully prevent any from occurring.

Fixes gitlab-com/operations#175
