In order to avoid confusion between Gitlab::Importers module and other
like named modules, this renamed it to Gitlab::DatabaseImporters.

Remove CommonMetricsImporter patch and change all references to
CommonMetrics::Importer. Move specs into their appropriate folders. Also
cleans up some common_metric importer namespacing.

This moves our metric importers into the lib folder. This will allow
them to be autoloaded instead of having to explicitly require them.

This refactors common metrics importer for two reasons. 1. To create a
new pattern that can be followed by future importers that will minimize
dependency collision and 2. To allow EE to more easily extend
dependencies.

Turns out push rules to validate commit message does
not apply in the context of automatic merge to
the refs/merge-requests/:iid/merge. Mainly because
if it fails to merge to it, we currently can't give enough
preemptive feedback to the user and it'll turn the
merge request unmergeable (given we automatically
mark it as unmergeable if we can't merge to the ref).

In general, it's a systematic operation, which already
bypasses user authorization and git hooks.

Therefore, this commit makes it bypass the push rules
at EE as well.
