fea8bb64ba Expose/Improve callback notification interface
This patch builds a small hierarchy of event objects that
represent the payload for callback notification events. The
overall goal of this work is to begin moving away from the
existing unstructured  **kwargs passed today and standardize
on a common set of event payload objects; the beginning of such
contained herein.

A PoC/dummy patch for neutron is provided in [1] that exemplifies
consumption of the new API by:
- Removes neutron.callbacks and moves all uses to
neutron_lib.callbacks.
- Neutron uses of callbacks for BEFORE_RESPONSE events
now use neutron-lib.
- Neutron uses of callbacks for ROUTER and PROCESS
resource events now use neutron-lib.
- Neutron UTs updated to pass with this patch.

For existing discussion on this approach please see [2][3].

1c92b539ff Add fixture for plugin directory
This is needed to stop stubbing out _get_plugin_directory
from neutron unit tests, thus preserving testing isolation.
