Andrew Laski 0152047a77 Add persistence to the RequestSpec object
In order to use the request spec for an instance boot during later
scheduling operations, like resize/migrate, it needs to be persisted.
This adds a db migration to store the request spec and methods to the
object to create/save/get the request spec.

The RequestSpec object is also important for cells v2 so that boot
requests can have their information persisted before the creation of an
instance record in the database.

Change-Id: I94cd50ad29e10eb320d1d78f3081db6519815ff9
Implements: bp persist-request-spec
