Add needs for all jobs which require setup-test-env and
move review-build-cng to additional stage review-prepare
to decrease wait time for jobs in pipeline

These files are not available in CE, resulting in CI pipeline failures
when trying to include these files. Since the job is already configured
to only run on EE, we can just include it in both CE and EE.

Having these defined in both CE and EE won't hurt anything.

MySQL support has been removed

Two static memory benchmarks will be included in our CI pipeline. It
will load gems from the Gemfile and check the amount of RAM consumed
as well as the number of objects allocated and retained.
Aggregated values will be included as 'metrics' into MRs while full
reports will be downloadable as job artifacts.

This commit adds CI job that validates all `*.yml`
with `yamllint`.

This commit fixes all offenses present in repository.

This reverts commit 744f1f2e, reversing

Also, play manual jobs once dependency jobs are done instead of polling
for the dependent jobs to be finished.

Given Rails doesn't use the Git binary anymore, this shouldn't be a
problem.

As described in
https://www.postgresql.org/docs/current/non-durability.html, we can save
money and time by disabling durability in tests.

In both e2e QA tests and unit tests, reduce the number of retires
to 2 (i.e., 1 initial and one retry)

Also, move MySQL tests to run only on master branch, and on schedules.

Instead of inserting a row after each example to an external database,
we save the CI profiling reports into the `rspec_profiling` directory
and insert the data in the update-tests-metadata CI stage.  This should
make each spec run faster and also reduce the number of PostgreSQL
connections needed by concurrent CI builds.

`scripts/insert-rspec-profiling-data` also inserts one file at a time
via the PostgreSQL COPY command for faster inserts. The one side effect
is that the `created_at` and `updated_at` timestamps aren't available
since they aren't generated in the CSV.
