[NOMERGE] buildbot & deps: remove
## ! This should not be merged until the necessary infra changes happen !

Removes buildbot and all python2 dependencies in the dependency tree that became unused as a result.

- buildbot
    - python-Jinja2
        - python-MarkupSafe
    - python-dateutil
    - python-sqlalchemy-migrate
        - python-tempita
        - python-SQLAlchemy
        - python-sqlparse
        - python-decorator
    - python-Twisted
        - Twisted (transitional dummy package)
        - python-openssl
        - python-service_identity
            - python-pyasn1-modules
                - python-pyasn1
            - python-cryptography
                - python-ipaddress
                - python-cffi
                    - python-pycparser
                        - python-ply
        - python-constantly
        - python-incremental
        - python-automat
        - python-hyperlink
            - python-idna
            - python-typing
        - python-PyHamcrest
- buildbot-slave

**Note:** buildbot does have new versions available that use python3, but the current direction that the infra is heading towards uses buildbot from PyPI directly, so I'm not sure if it should be updated or removed.

Also, should most of the `python3-` packages that have changed in this PR be revbumped? I've locally verified that the package contents are the same except in a few cases.
