History
Sylvain Bauza 09f2d4d5ec Add a RequestSpec generation migration script 
In Mitaka, we began to create and persist a RequestSpec object every time
a new instance was requested. Given that instances that were created before
that commit do not have a related RequestSpec, we needed to check
every time in the conductor methods whether the instance had a request spec
associated with it.

Now that we are in Newton, we can provide an online data migration script
that iterates over all the instances (using a marker), verify if the
RequestSpec object is created, and if not, try to persist into that object
the legacy fields we already know.

The marker uses the request_specs table for persisting itself, and
yes this is a hack, but that's the only solution we agreed for making sure
we were not looping every time on all the instances (which would be a
performance problem). When we finish looping over the instances, we
keep that marker so that the next call to that migration script
would not again iterate over all the instances (using the limit).
