Code Issues Proposed changes

Add new APIs and deprecate old API for migrations 

This patch does two things:
1. Add two APIs /servers/migrations:index/show for server migrations.
Two new novaclient commands server-migration-list and
server-migration-show will also be added.
ref: I071198fa9ba0699383bdebf4fab54714a435e6c3

2. Add ref link for /os-migrations
The old top-level resource `/os-migrations` won't be extended anymore.
It is deprecated.
Adding migration_type for it, also add ref link to
/servers/{uuid}/migrations/{id} for it when the migration is an
in progress migration.

Partially implements blueprint live-migration-progress-report

----
From this version of the API users can get the migration summary list by
index API or the information of a specific migration by get API.
And the old top-level resource `/os-migrations` won't be extended anymore.
Add migration_type for old /os-migrations API, also add ref link to the
/servers/{uuid}/migrations/{id} for it when the migration is an in-progress
live-migration.

deprecations:
-
The old top-level resource `/os-migrations` is deprecated, it won't be
extended anymore. And migration_type for /os-migrations, also add ref
link to the /servers/{uuid}/migrations/{id} for it when the migration
is an in-progress live-migration. This has been added in microversion
2.23.
