Switch jobs to py3

- removed `USE_PYTHON3` from ironic-ipa-base since ironic-base
already has this configuration

- Enabled python3 for ipa-tempest-wholedisk-bios-ipmi-direct-tinyipa-src
and ipa-tempest-partition-bios-ipmi-direct-tinyipa-src

- Renamed ipa-tempest-dsvm-partition-ipmi-iscsi-tinyipa-python3 to
ipa-tempest-dsvm-partition-ipmi-iscsi-tinyipa
