In microversion 2.80, the ``GET /os-migrations`` API will have
optional ``user_id`` and ``project_id`` query parameters for
filtering migrations by user and/or project:

* GET /os-migrations?user_id=ef9d34b4-45d0-4530-871b-3fb535988394
* GET /os-migrations?project_id=011ee9f4-8f16-4c38-8633-a254d420fd54
* GET /os-migrations?user_id=ef9d34b4-45d0-4530-871b-3fb535988394&project_id=011ee9f4-8f16-4c38-8633-a254d420fd54

And expose the ``user_id`` and ``project_id`` fields in the following APIs:

* GET /os-migrations
* GET /servers/{server_id}/migrations
* GET /servers/{server_id}/migrations/{migration_id}

The ServerMigrationSampleJsonTests functional tests set up
``self.api.microversion`` to 2.22 in its' setUp(), which use
sample files from non version dir.

For consistency, this commit makes these tests to use sample
files from versioned dir.

The ServerMigrationSampleJsonTestsV2_24 functional tests set up
``self.api.microversion`` to 2.24 in its' setUp(), by doing this
it will not need to add its' own sample files, as there will be
no difference anyway. But this makes Tests that inherent from this
test class impossibe to run as the microversion will always been
overriden.

This patch fix it by change the tests to use self.microversion and
adds its' own sample files.

This patch adds pagination support and changes-since filter
for os-migrations API.

Users can now use 'limit' and 'marker' to perform paginate
query of running migrations list. Users can also filter the
results according to the migrations' updated time.

The ``GET /os-migrations`` and server migrations APIs will now
return a uuid value in addition to the migrations id in the response,
and the query parameter schema of the ``GET /os-migrations`` API no
longer allows additional properties.

Closes-Bug: #1641988

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.
