Raise ApiError in response to InstanceTypeNotFound

 * Updates methods in nova.compute.instance_types to catch
   InstanceTypeNotFound exceptions and re-raise them as ApiError.
   - Previously, the methods in instance_types were raising ApiError in
     response to DBError, but the underlying db calls have since been
     updated to detect empty results and throw more specific exceptions.
 * Updates get_instance_type_by_flavor_id to not try to catch DBError,
   as the underlying db call only ever raises FlavorNotFound.
   get_instance_type_by_flavor_id should not raise ApiError, as callers
   expect the FlavorNotFound exception and know how to handle it.
 * Fixes bug 872618
