This ensures ProjectCacheWorker jobs for a given project are performed
at most once per 15 minutes. This should reduce disk load a bit in cases
where there are multiple pushes happening (which should schedule
multiple ProjectCacheWorker jobs).

## What does this MR do?

## What are the relevant issue numbers?

Closes #23555

See merge request !7007

Differentiate the expire from leave event

At the moment we cannot see whether a user left a project due to their
membership expiring or if they themselves opted to leave the project.
This adds a new event type that allows us to make this differentiation.
Note that is not really feasible to go back and reliably fix up the
previous events. As a result the events for previous expire removals
will remain the same however events of this nature going forward will be
correctly represented.

Closes #22611

Also, as part of this fix, I removed applications of `-webkit-overflow-scrolling: auto` in two other places where they're no longer needed. One was the file-holder. I made sure I could reproduce the behavior this was intended to fix, and then made sure this MR still fixed it. 

Here's the errant behavior:

Merge branch '22457-reset-filters-button-should-be-invisible-when-no-filters-are-active' into 'master'

`Reset filters` link should only be visible when filters are active

## Why was this MR needed?

`Reset filters` link is always visible.

Closes #22457

See merge request !6497

Fixed all related specs and also changed the logic to handle edge cases. This includes exporting and exporting of group labels, which will get associated with the new group (if any) or they will become normal project labels otherwise.

Found other issues to do with not being able to import all labels at once in the beginning of the JSON - code was much simpler when we import all labels and milestones associated to a project first, then the associations will find the already created labels instead of creating them from the associations themselves.
