[LBaaS] test_models_sync is skipped in UT due to the backend unavailability

[Elena Ezhova]

According to [1] access to MySQL/PostgreSQL is no longer in unittests by default. That's why tests for models and migrations sync are currently getting skipped in neutron-lbaas. Model migration tests should run as functional tests like they do in neutron and fail if db backend is unavailable, unless OS_FAIL_ON_MISSING_DEPS is disabled.

    Refactor gate hooks

    The aim of this change is to make gate_hook and post_test_hook
    more generic and prepare base for adding a new functional job
    and tests. The patch also includes a number cosmetic changes
    which should make the hooks' code easier to read.

    - Moved all argument parsing to decode_args.sh.
    - gate_hook: Extracted code related to configuring Octavia into a
      separate function.
    - post_test_hook: Filling test_subset is not required if the aim
      is to run all set (api-* job).
    - post_test_hook: Don't set OS_TEST_PATH and OS_TESTR_CONCURRENCY
      as it's also done in tox.ini.
    - Style fixes.

    Fix stable/mitaka gate failures

    This change is squashed from backports of
    0b6a3fbdfab9768287205d278061a63204869e5d and
    b68c0e27e3f52238dce048ead2538fdabe179e06. These two bugfixes
    form a circular depencency and can't be merged without each
    other.

    The other way to solve this deadlock is to revert
    https://review.openstack.org/322811 and
    https://review.openstack.org/320998, merge
    https://review.openstack.org/321563 and then start
    anew.

    Here are the commit messages of both changes:

    Neutron-LBaaS: Fix network_resources path

    * upstream tempest changed the namespace for
      network_resources, this change updates that path
    * fixed changed deprecated config parameters
    * replaced network_cilent passed into DeletableSubnet
      with subnets_client and routers_client

    Set up hooks for the functional job and add test_migrations test

    Add gate hooks for the dsvm-functional job including set-up of
    configure_for_lbaas_func_testing.sh script and corresponding changes to
    tox.ini.

    PyMySQL dependency was moved from test_requirements.txt to
    functional/requirements.txt.

    test_migrations.py was moved from unit tests to functional in
    order to prevent it from being skipped in case of db backend
    unavailability.

    Fixed failing TestModelsMigrations test by importing modules with
    missing models in db/models/head.py
