    Skip tests to update u-c for PyMySql to 0.10.0

    In the new version of PyMySql the error > 1000, will be
    operational error [1], which is failing keystone migration
    test cases [2] for backend mysql because we raise dberror
    [3] which does not handle operational error.

    PyMySQL hasn't been raised to 0.10.0 in the upper-constraints
    yet, so this patch isn't going to be able to install it.
    We can't raise the u-c since the current keystone jobs are
    failing with it.

    This patch overrides the test cases for backend SQL and skips
    the same. This is so to make sure that failed test cases are
    skipped because Once the upper-constraints are updated to
    0.10.0 for PyMySql and merged, will revert the skip and
    handle for 0.10.0.
