- remove git clone progress reporting (reduce CI noise)
- report current user

- no random ports
- use separate rabbitmq.conf file on github
- ci: temporarily disable all but ci-integration
- ci: cp ssl_certs into rabbitmq container
- reenable management plugin
- manual custom.conf
- add python-version for ci-integration tests
- add default rabbitmq user/pass
- do not hardcode RMQ user/pass in tests
- override more rabbitmq test urls
- fix integration test conf files on the fly
- go back to guest:guest with rabbitmq
- finish reverting rmq guest:guest stuff
- Reconfigure RabbitMQ for ci-unit tests as well

If a virtualenv was built with symlinks instead of copies of the python
binary, as happens by default on GHA integration tests, then we end up
using the system virtualenv binary instead of what we installed.

Currently GHA has the same version of virtualenv, but we build
virtualenvs with --system-site-packages, and we need it to use the st2
virtualenv as the "system" dir instead of the GHA provided one. So,
don't get the realpath of the python binary.

Also, fall back to system virtualenv bin for backwards compat.

- install virtualenv in --user
- pip uninstall --user
- Try to recreate failure on Travis
- leave TODO/FIXME around broken test

- Use close_fds=True.
- add workaround for failing test

When we updated pip, we missed updating pip-tools to support the newer
pip version, so there were errors (that didn't fail the build, oops)
like these (fixed in pip-tools 5.4, pip-tools-PR-1216:
