Fix notes email with group-level notification email

Closes #63355

See merge request gitlab-org/gitlab-ce!29889

A Noteable doesn't have a group directly, unless it's an epic - we need
to look for the project's group to find the right email address.

Docs: link to predefined env variables reference more evident

Closes #62845

See merge request gitlab-org/gitlab-ce!29857

This `ignore_column` was present for a while but recently removed, but
to ensure we don't get error 500s let's keep it for a while.

We now create_deployment on Ci::Build create.
No need to call create_deployment again

This saves about 5 SQL calls per page if no custom appearance is
specified.

This eliminates many potential duplicate FindCommit RPCs for the same
ref, which often occurs in the RelativeLinkFilter#current_commit call.
On the GitLab 12.0 release post, for example, this would save close to
400 RPC calls.
