Use Tempest plugin interface

Make use of the Tempest plugin interface.

This patch set creates some directories and files for
Tempest plugin interface which are generated by
tempest-plugin-cookiecutter(See [1] and [2]),
which uses ironic_tempest_plugin as new top folder for all Tempest tests,
and also makes possible to import config values from Tempest and use them.

Copying Ironic tests in Tempest to Ironic tree and removing
existing Ironic tests in Tempest will be done after merging this
patch set.
