Including tasks has a performance penalty when compared with importing
tasks. If the include has a condition associated with it, then the
overhead of the include may be lower than the overhead of skipping all
imported tasks. For unconditionally included tasks, switching to
import_tasks provides a clear benefit.
Benchmarking of include vs. import is available at [1].
This change switches from include_tasks to import_tasks where there is
no condition applied to the include.

'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.
