Tracking of custom events ## What does this MR do? This MR adds the ability to track custom events such as the number of Git pushes. ## Are there points in the code the reviewer needs to double check? The usual stuff. ## Why was this MR needed?

GitLab Performance Monitoring is now able to track custom events not directly related to application performance. These events include the number of tags pushed, repositories created, builds registered, etc. The use of these events is to get a better overview of how a GitLab instance is used and how that may affect performance. For example, a large number of Git pushes may have a negative impact on the underlying storage engine. Events are stored in the "events" measurement and are not prefixed with "rails_" or "sidekiq_", this makes it easier to query events with the same name triggered from different parts of the application. All events being stored in the same measurement also makes it easier to downsample data. Currently the following events are tracked: * Creating repositories * Removing repositories * Changing the default branch of a repository * Pushing a new tag * Removing an existing tag * Pushing a commit (along with the branch being pushed to) * Pushing a new branch * Removing an existing branch * Importing a repository (along with the URL we're importing) * Forking a repository (along with the source/target path) * CI builds registered (and when no build could be found) * CI builds being updated * Rails and Sidekiq exceptions Fixes gitlab-org/gitlab-ce#13720

Added documentation on adding database indexes ## What does this MR do? This MR adds a guide on when to add database indexes, how to approach this problem, etc ## Are there points in the code the reviewer needs to double check? Spelling, grammar, etc ## Why was this MR needed? Blindly adding indexes can be harmful to the database, and I recently had to remove 48-something unused indexes. ## What are the relevant issue numbers? #20767 ## Does this MR meet the acceptance criteria? - [x] [Documentation created/updated](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/development/doc_styleguide.md) - Tests - [x] All builds are passing - [ ] Conform by the [style guides](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/CONTRIBUTING.md#style-guides) - [x] Branch has no merge conflicts with `master` (if you do - rebase it please) - [x] [Squashed related commits together](https://git-scm.com/book/en/Git-Tools-Rewriting-History#Squashing-Commits) See merge request !5771
