The grafana local admin username can be configured by overriding
the admin user field in the grafana.ini file. However, this will
fail when kolla-ansible attempts to configure any enabled
datasources for grafana because the local admin password is
hardcoded to 'admin'. This change allows the grafana local admin
password to be configured via group vars so that the correct
username is used when configuring datasources.

Murano failed to deploy due to outdated options - it tried to

are similar to other projects deployment succeeds.

'deployment' hosts don't need api interface. Previous fix checked
if hosts belong global groups like [compute] or [control] which
is not correct because uses can create own groups and the check
won't work there at all. Here the logic is reversed - we blacklist
groups that don't need api_interface.

If control hosts have different names of interfaces one can set
api_interface variables per host. Deployment of keystone fails
because rpc_transport_url and notify_transport_url variables
use bare api_interface instead of one from hostvars.
