AES-256-GCM cipher mode requires a key that is exactly 32 bytes long.
We already handle the case when the key is too long, by truncating, but
the key can also be too short in some installations. Switching to a key
that is always exactly the right length (by virtue of right-padding
ASCII 0 characters) allows encryption to proceed, without breaking
backward compatibility.

When the key is too short, encryption fails with an `ArgumentError`,
causing the web hooks functionality to be unusable. As a result, zero
rows can exist with values encrypted with the too-short key.

When the key is too long, it is silently truncated. In this case, the
key is unchanged, so values encrypted with the new too-long key will
still be successfully decrypted.

It appears that for some jobs
(https://gitlab.com/gitlab-org/gitlab-ce/-/jobs/129705025 for example)
we process a range of commits far greater than necessary, which can lead
to commits getting reverted that were merged a long time ago.

Previously we used @user, but this changed to local_assigns[:user]
so we could pass a second variable to the view from an EE module

Since we were already using current_user librally there it makes sense
to replace the remaining usages.

Currently, if a job does not have only/except policies, the policy is considered as an unspecified state, and therefore the job is executed regardless of how it's executed and which branch/tags are targetted.
Ideally, this should be specified as only: ['branches', 'tags'], as it indicates that unspecified policy jobs are meant to run on any git references.

This updates the documentation of automatic CE to EE merges to cover the
new automatic merging setup.

This sets up GitLab CI to automatically push CE master changes into EE
master, or revert them if the changes cause merge conflicts. The CI
configuration contains a single job to do this: `merge:master`. This job
is executed for every push to master, and periodically using a CI
schedule.

The periodic job is necessary because incremental jobs may not be able
to revert commits if newly added commits depend on these commits. By
re-running the job periodically (including all changes since a large
enough time frame), we can ensure that such commits are also reverted
(if they still conflict at that time).

The job runs in its own "merge" stage, _after_ the build and prepare
stages, but _before_ running the tests. This ensures that randomly
failing tests won't prevent code from being merged into EE. Running the
stage after the "prepare" stage reduces the chances of the job reverting
CE changes just because it ran before a corresponding EE MR was merged
into EE master.
