Fuel does not allow to deploy environment without controllers and gives error like this:

Error: Not enough controllers, ha_compact mode requires at least 1 controller(s)

This blocks any possibility to deploy deeply customized configurations using Fuel Plugins. For instance: I may want to introduce brand new role that will replace our standard controller role and use this role in my deployment. But Nailgun will not allow this.

Steps to reproduce:
1) Create env without controllers (for example with 1 compute)
2) Deploy changes

Expected result:
Some kind of warning about possible problems and started deployment process

Actual result:
Deployment is not started, "Not enough controllers, ha_compact mode requires at least 1 controller(s)" is shown
