**Bug Report**

I installed the core services of Openstack(currently eval AIO) using master branch of kolla and kolla ansible.
After first fire up I activated AODH, gnocchi and ceilometer.

What happened:

I as far as I can see the issue is related to gnocchi_upgrade und ceilometer_upgrade.
Both commands are run with '' as parameter which cannot be interpreted ("+++ ceilometer-upgrade ''",).

What you expected to happen:
ceilometer_upgrade and gnocchi_upgrade get no parameter attached if BOOSTRAP_PARAMS is empty.

How to reproduce it (minimal and precise):

set up openstack with "out-of-the-box" Kolla and kolla-ansible while activating ceilometer in globals.yml.
