- Allow ARA installation to be disabled in gate-check-commit. For
backwards compatibility, this remains defaulted to true. However
in the OSA gate, the pre-run playbook will install ARA so we set
it to false during the gate-check-commit run rather than waste
time installing it twice.
- Separate the ARA installation from loading. Continue installing
ARA using the setup_ara function, but do not load ARA into the
callback plugins env var there. Instead, we will load ARA into
the ANSIBLE_CALLBACK_PLUGINS inside the openstack-ansible wrapper
if it is installed.
- Move ARA installation function call to run right after the
ansible-runtime venv is created. This makes little difference
except that ARA will now be installed in time for the
get-ansible-role-requirements role clone run.
