Allow personal access token env var from gitlab-qa

See merge request gitlab-org/gitlab-ce!24048

gitlab-qa accepts an env var named GITLAB_QA_ACCESS_TOKEN, but here we
only accepted PERSONAL_ACCESS_TOKEN.

This change replaces PERSONAL_ACCESS_TOKEN with GITLAB_QA_ACCESS_TOKEN

Properly handle `ee` migration specs

See merge request gitlab-org/gitlab-ce!26685

[CE] Reduce diff with EE in `spec/policies`

See merge request gitlab-org/gitlab-ce!26593

For some reason this value can be an empty string and we want to ensure
that we correctly fail the job before a deploy. This is particularly
problematic at the moment when coupled with
https://gitlab.com/gitlab-org/gitlab-ce/issues/54760 as the user has no
easy way to recover without destroying the cluster and starting over.

Update U2F recommendations, fix #57656

Closes #57656

See merge request gitlab-org/gitlab-ce!25709

Rename build to job in webhooks docs

Closes #42254 and #28226

Refactor verify_pages_domain_service specs

See merge request gitlab-org/gitlab-ce!26178

Add specs for new/disabled pages domain
Extract contexts from examples
Use `let` instead of `set` since domain is being changed
in each example

[QA] Toggle Gitaly N+1 detector via feature flag and run tests

Closes gitlab-qa#374

See merge request gitlab-org/gitlab-ce!26060

First attempt at allowing a feature flag to be set via the command line
when running tests. This will enable the flag, run the tests, and then
disable the flag.

Using OptionParser meant changing how scenarios get the instance
address, so this also allows the address to be set as a command line
option. It's backwards compatible (you can still provide the address
as the command line option after the scenario)

Update bootstrap to 4.3.1

Closes #52091

See merge request gitlab-org/gitlab-ce!25911

Since external diffs are likely to be a bit slower than in-database
ones, add a mode that makes diffs external after they've been obsoleted
by events. This should strike a balance between performance and disk
space.

A background cron drives the majority of migrations, since diffs become
outdated through user actions.

The new version requires `python3` to be available. In omnibus
installation this is already a reality as we are currently pathing
previous `gitlab-markup` version to use `python3` instead of `python2`.

We are now requiring `python3` with the gem without having to patch it.

As a consequence to also make it easy to use it in development, we've
introduced a `Pipfile` and `Pipfile.lock`, working similarly to
`Gemfile` and `Gemfile.lock`, and added documentation on how to use
them.
