This commit does the following:
- removes tempest_git_repo since this is the default in the tempest
role
- removes tempest_git_dest since this variable is no longer used in
os_tempest
- adds tempest_venv_tag variable so tempest venv is created in
/opt/tempest_master instead of /opt/tempest_untagged
- updates tests/test-nova-functional.yml to use {{ tempest_venv_bin }}
NOTE: We also remove the local connection from
test-prepare-containers.yml as we were seeing unexpected behaviour with
this in place (such as the host getting a container's hostname, etc.)
