Fix containerized tempest logic

We weren't testing containerized tempest in standalone job due the
missing logic on tempest-setup.sh script. This patch adds the logic for
when containerized tempest runs in standalone, copying the clouds.yaml
file instead of the stackrc/undercloudrc and also maintain the logic
when you execute tempest in the ovb, copying the rc file.
This also ensures that /var/lib/tempestdata and /var/log/tempest
directories exists in order to not fail the execution of containerized
tempest.
