Replace comment by variable

See merge request gitlab-org/gitlab-ce!27007

Instead of having a comment describing what a specific value is,
better to have a variable with a meaningful name.

Port of 57602-create-cluster-validations to EE

See merge request gitlab-org/gitlab-ee!10467

In the new cluster forms, display form error messages
below form fields instead of a summary banner on top
of the form.

Include client side validation in order to display
user friendly error messages.

Also remove unnecessary placeholders.

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26248 added
support for deduplicating FindCommit requests using Gitaly ref name
caching. However, not all endpoints were covered, and in one case the
Gitaly wrapper wasn't actually surrounding the serialization step. We
can safely cache ref names between FindCommit calls for #index and #show
endpoints for merge requests and pipelines. This can significantly
reduce the number of FindCommit requests.

Rename Workhorse terminal_specification to channel_specification

See merge request gitlab-org/gitlab-ce!26939

We're moving from using terminology related to terminals when
we refer to Websockets connections in Workhorse.
It's more appropiate a concept like channel.

Allow reactive caching to be used in services

See merge request gitlab-org/gitlab-ce!26839

Add support for defining a reactive_cache_worker_finder function
that will be used by the reactive_caching_worker to generate/initialize
the calling object. This allows reactive caching to work with Services
where the object cannot be obtained from DB but a new object can be
initialized.
