Keystone project manager role can be used for the project-level
management APIs. Nova introduced the manager role in policy
defaults.
To introduced the manager role, we need to make migrations
policies more granular. Adding the separate policies for host
related operation allow us to open the migration operations
to project manager role. Existing policy is checked if migration
without specifying host and new policy is checked if host is
specified. Same will be applied to list migrations, new policy
will control to return the host info.
Also, Adding doc and releasenotes.
