Temporarily disable test_manage_invalid

This test stops making sense as-is when running against
https://review.openstack.org/635831. The test tries
to create a share with a share type configured with a
driver mode that was unsupported by this API. Since it
becomes supported in https://review.openstack.org/635831,
the test fails because an error is no longer returned by
the API.

The Manage/Unmanage share test cases are being reworked
as part of the implementation of the
Manage-Unmanage with Share Servers feature and are to be
found in a separate patch dependant on this one.
