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%' Change-Id: I79251dde719b4bb5c3b0cce90d0c9d1581ae66f2
