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.
