huangtianhua 5b04acb4e2 To reset metadata for resources when mark unhealthy
Some resources do not work if their metadata is in
a wrong state, .e.g the metadata 'scaling_in_progress'
of scaling group/policy might be always True if engine
restarts while scaling.
This patch adds an interface 'handle_metadata_reset' for
resource, then the plugins can override it if needed.
We reset the metadata while marking resource healthy.

Heat is a service to orchestrate multiple composite cloud applications using templates, through both an OpenStack-native REST API and a CloudFormation-compatible Query API.

Why heat? It makes the clouds rise and keeps them there.
