kolla-ansible reconfigure fails when manila is enabled

It looks like it fails because some items are skipped in steps "Check the configs" and "Containers config strategy". Because of this, the item[1] (container_envs.results) cannot have the 'KOLLA_CONFIG_STRATEGY' defined.
Why these items are skipped? Because part of the manila components are deployed on the controller ansible group, and the other part on the storage ansible group, which is ok I guess.

From the code analysis it seems that this is not only manila-related problem. The same problem may occur with other components, when someone will try to customize placement of the component "subelements". For example:
# Murano
[murano-api:children]
host001
[murano-engine:children]
host002

Affected components list:
* ceilometer
* glance
* heat
* ironic
* magnum
* mistral
* murano

Solution: change the order of "when" statements and bring "inventory_hostname in groups[item[0]['group']]" to the top.
