Fix https://gitlab.com/gitlab-org/gitlab-ce/issues/30637

Closes #31095

This table shows the percentage of users who registered in the last
twelve months, who last signed in during or later than each of those
twelve months, by month.

It is only enabled when the usage ping is enabled, and the page also
shows pretty-printed usage ping data.

The cohorts table is generated in Ruby from some basic SQL queries,
because performing the gap-filling and running sums needed in both MySQL
and Postgres is painful.

CE port of https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/735

Enables user specification of group name vs. name inferred from group path.

Cause new group form to copy name from path

Adds some new page-specific javascript that copies entry from the
group path field to the group name field when the group name field
is initially empty.

Remove duplicate group name entry field on group edit form

This corrects the duplicated name entry field and tests that the
JavaScript does not update the group name field if the user
edits the group path.  (Editing the group path is not recommended
in any case, but it is possible.)

Address eslint errors in group.js

Enable group name copy with dispatch and explore group creation

The dispatch and explore group creation forms require the group.js
asset, and their tests now require testing against poltergeist

Update workflow new group instruction

Update the gitlab basics group creation document

Add a change log entry

Remove unused variable for eslint

desired decimals for the cpu metrics

Cleaned up some code

Fix https://gitlab.com/gitlab-org/gitlab-ce/issues/19742

Now you can create a new file and select a target_branch != source_branch.
If the file that you want to create already exists on the target branch an error message is shown
A glDropdown is used to select and create a new branch instead of a text field.

Removes `:visible` from selector
Adds CHANGELOG entry
Removes iife

Also modified the render calls to the deploy_keys and protected_branches
partials

Reuse same search form and behavior for dashboard#projects, group#projects
and admin#projects. Repsect all other options like sorting, personal
filter when search projects by name. Create FilterableList JS class to
handle identical behaviour of projects and groups lists.

This change also makes filtering and sorting availabe on explore#projects
and explore#groups no matter if you are logged in or not.

Also improved accesibility and change the id from user_callouts to a class

after user click delete branch, there is no processing indication, and user can click many times till. It seems flaw in UX. this will fix it
