Reorganize metrics dashboard

See merge request gitlab-org/gitlab-ce!31006

In preparation for embedding specific metrics in issues
https://gitlab.com/gitlab-org/gitlab-ce/issues/62971,
this commit moves the BaseService for metrics dashboards
to a new services subdirectory. This is purely for the sake
of organization and maintainability.

Migrations for adding issue_id to versions table (CE)

See merge request gitlab-org/gitlab-ce!30765

These migrations do the following:

- Adds a new `issue_id` column to `versions`. This fixes an n+1 problem
  when loading versions for an issue in GraphQL as AR can now load from
  cache
- Change the unique restraint on versions.sha to be scoped to `issue_id`
  as in order to import version data, we need to allow duplicate `sha`
  values for versions
- Update all versions with an `issue_id`
