Setup project members Vue application

Convert HAML project members view to new Vue layout that matches group
members layout

In build_service.rb, let's refactor some param processing code
and comments from the execute() method into a new
filter_label_id_params() method.

While at it let's also add a few comments.

In build_service.rb, let's move most of the force_remove_source_branch
handling code into a new force_remove_source_branch() method.

In issuable_base_service.rb the code processing labels is making
the update() method not as clear as it could be. Let's refactor
this code into a new assign_requested_labels() method.

While at it, lets rename labels_changing? into ids_changing?
as the method is not specific to labels and could be used with
other arrays of ids.

Instead of having to use a local variable in many places in
push_options_handler_service_spec.rb for the same error, let's
refactor this error using a common constant called
'error_mr_required'.

Remove specific date in audit events spec

Delete old redirect files in various docs directories

See merge request gitlab-org/gitlab!52997

These redirect files have expired and we
no longer need to maintain them. Server-side
redirects will remain in the gitlab-docs project

By default, the audit event search results are limited to the current
month. Having records created beyond that time range requires setting
the date filter or else they will not show up in the page.

The specific broken specs do not test date filter or order logic. Hence,
we could remove these dates.
