To fix the merge requests failing to match due to replication lag
(https://gitlab.com/gitlab-org/gitlab/-/issues/247857) we added a
mechanism to track the WAL pointer of the merge request to decide
whether to use the secondary or fall back to the primary. This commit
adds metrics to better understand how often this fallback is occurring.

Allow optional caching in failed builds

See merge request gitlab-org/gitlab!41822

`cache:when` is used to cache on job failure, despite the failure.

`cache:when` can be set to one of the following values:

1. `on_success` - upload artifacts only when the job succeeds.
   This is the default.
2. `on_failure` - upload artifacts only when the job fails.
3. `always` - upload artifacts regardless of the job status.

Abstract keybinding to allow keyboard shortcut customization

See merge request gitlab-org/gitlab!44527

This commit updates the way in which we bind key sequences to functions
when implementing keyboard shortcuts.

Before this commit, developers would directly bind a key sequence to a
handler:

```js
Mousetrap.bind('p b', handler);
```

After this commit, developers will instead define a new "command" in
`~/behaviors/shortcuts/keybindings.js` and bind to the result of
`keysFor(command)`:

```js
import { keysFor, TOGGLE_PERFORMANCE_BAR }
from '~/behaviors/shortcuts/keybindings.js';

Mousetrap.bind(keysFor(TOGGLE_PERFORMANCE_BAR), handler);
```

`keybindings.js` handles returning the appropriate key sequence for
the command (or it returns `[]` if the command is disabled).
