Enable per-role SchedulerHints
This adds a parameter for each role, where optional scheduler hints
may be passed to nova. One potential use-case for this is using
the ComputeCapabilities to pin deployment to a specific node (not
just a specific role/profile mapping to a pool of nodes like we
have currently documented in the ahc-match docs).
This could work as follows:
1. Tag a specific node as "node:controller-0" in Ironic:
ironic node-update <id> replace properties/capabilities='node:controller-0,boot_option:local'
2. Create a heat environment file which uses %index%
parameters:
ControllerSchedulerHints:
'capabilities:node': 'controller-%index%'
