Comment 4 for bug 1649889

I've removed tasks that caused cycles, and it helped to start deployment.
However it still fails, because plugin roles got broken with recent updates.

There's a role `contrail-controller` with `has_primary: true`, but in the env with one such node it turned to be non-primary:

root@node-1:~# hiera roles
["contrail-controller"]

This breaks tasks execution sequence.
