Add back Gitaly feature flag for cache invalidation

See merge request gitlab-org/gitlab!22106

Part of https://gitlab.com/gitlab-org/gitaly/issues/2292

Related to https://gitlab.com/gitlab-org/gitaly/issues/2288

This change is essentially a revert of
https://gitlab.com/gitlab-org/gitlab/merge_requests/18766. Due to an
issue found in production (see
https://gitlab.com/gitlab-com/gl-infra/production/issues/1501#note_262058610),
the cache invalidator needs to be disabled until the cache walker is
able to remove empty directories. This feature flag will allow us to
reenable the cache invalidator when we are ready to test the updated
cache walker.

Fix setup order in Elasticsearch docs

See merge request gitlab-org/gitlab!21930

The deployment of
https://gitlab.com/gitlab-org/gitlab/merge_requests/20154 broke new
deployments of GitLab Pages. The call to
`project.feature_available?(:pages_size_limit)` failed with this error:

```
Use `License.feature_available?` for features that cannot be
restricted to only a subset of projects or namespaces
```

Since `GLOBAL_FEATURES` includes `pages_size_limit`, we must call
`License.feature_available?(:pages_size_limit)` instead to be consistent
with `EE::GlobalPolicy`.

Replace Vue key=index in licenses list table

See merge request gitlab-org/gitlab!21566

**Why?**

In Vue, lists are not re-rendered, but patched when new props come. This
can cause issues when items which are actually different share the same key.

Remove after_initialize, before_validation for discussion_id on Note

See merge request gitlab-org/gitlab!22128

- We're already overridding the `discussion_id` method in Note.  The
  after_initialize callback is meant to ensure there's a discussion_id
  for all notes if there wasn't one created (or it got deleted?)

- after_initialize runs Ruby code for _every_ instantiation whether it
  needs to or not.  I've found this to cause performance problems.
