This commit includes three changes.
The first is a change to  requirements.yml to no longer consider python
versions < 3.8
The second addes a note to the container image build workflow regarding
changes to labelling that may affect it.
The third updates references to ``ironic_pxe`` to ``ironic_tftp``.
