Remove unused Usage Quotas tab initiation js files

What does this MR do and why?

These files should've been removed in Cleanup Feature Flag: usage_quotas_for_all_edit... (!149041 - merged)

With the Feature Flag being removed, Usage Quotas tabs don't use these file to render anymore. The render happens with:

1. Div with id #js-usage-quotas-view in the haml file: Group, Project, Profile
2. This div will be selected to load the Usage Quotas View App: Group, Project, Profile,
3. The Usage Quotas View App Initializator will load tab_metadata depending on the view_type (Group, Project, or Profile)
   1. These metadata differ per view type, and per GitLab distribution (e.g. CE group_view_metadata vs EE group_view_metadata
4. Each Page view metadata will include the necessary tab initiator, that does the job that the files being deleted in this MR used to do, example: Pipelines tab_metadata
