In https://gitlab.com/gitlab-com/gl-infra/infrastructure/issues/8511
and https://gitlab.com/gitlab-com/gl-infra/production/issues/1309
we have seen cases where sidekiq-cluster has been asked to restart,
but it has left one or more sidekiq worker processes in a stuck/hung
state burning CPU.

With this, sidekiq-cluster now waits for the worker processes to
terminate themselves cleanly (and push jobs back onto the queue) and
another few seconds beyond, then if any processes remain, kills them
hard (:KILL signal) before exiting as usual (allowing whater process
monitor is in place to restart sidekiq-cluster)

`_placeholder` refers to a temporary element that appears while
content is loading. For example, the elements that are displayed
instead of discussions while the discussions are being fetched.

`_container` refers to an element that includes other elements, but
might not include any visible content itself. E.g., an element that
has a third-party editor inside it, but which isn't the editor itself
and so doesn't include the editor's content.

`_modal` refers to a popup modal dialog, e.g., a confirmation prompt.

Refactor `wait` and `retry_*` methods

See merge request gitlab-org/gitlab!21804

This is the first step in refactoring the Waiter and Retrier modules

* Moves wait into the Retrier module as wait_until, and renames
  the max parameter to max_duration, to convey that its purpose
  is similar to retry_until.
* Combines the loop logic into a single private method that the
  different public wait/retry methods use.
* Allows retry_until to retry up to a certain maximum time limit,
  like wait_until, as well as the original funtionality of waiting
  until a specified condition is met.
* Adds a retry_on_exception parameter to so that it's not necessary
  to nest wait/retry blocks if you want to do both.
* Adds a raise_on_failure parameter, which is the same as
  retry_until's exit_on_failure parameter, but now it can be used
  with wait_until.
