This fixes an issue where the Rails autoload system would throw various `Unable to autoload constant` errors (such as `Unable to autoload constant EE::ProjectsHelper`) when using the autoload system (such with `spring` or `reload!` in the rails console.

This error was specifically ocurring in the EE code, however, it's seems reasonable to place the fix in CE as a general innoculation.

This ensures that we have more visibility in the number of SQL queries
that are executed in web requests. The current threshold is hardcoded to
100 as we will rarely (maybe once or twice) change it.

In production and development we use Sentry if enabled, in the test
environment we raise an error. This feature is also only enabled in
production/staging when running on GitLab.com as it's not very useful to
other users.

Implements the client side for gitlab-org/gitaly#819. Which is a server
info command. This checks the server version and git binairy version on
the server.

A small UI was added for administrators, so they can check the status of
the Gitaly server. This is done for each storage the monolith knows.

Because of this commit, gitlab-org/gitlab-ce!15580 is now closed. That
MR removed the Git version too, but didn't replace it with anything.

Bringing in https://github.com/reprah/grape-route-helpers/pull/21 as a
monkey patch since the grape-route-helpers project seems to be abandoned
