tempest test class manila_tempest_tests.tests.api.admin.test_migration.MigrationNFSTest is very slow

[Valeriy Ponomaryov]

Commit [1] added 6 new "migration" tests to the same class. All of them are pretty slow - 2-2,5 minutes. And all of them always run in the same thread, serially. It make tempest run take about 20 minutes just because of this single thread. There is no need to run these tests serially. So, we need to split them up to separate classes, so they could be picked up by different threads and run in parallel.

    [Tempest] Split up share migration tests to separate classes

    All tempest tests that are located in single class always run
    serially. And one of our classes that performs lots of different
    share migration tests takes about 20 minutes. So, split them up
    to separate classes to speed up test run.

    This fix also includes a trivial optimization to the 'opposite driver

    commit 1181a80bf6473d3fe7ed83c0b1df7c738c2a71e5.
