Install additional oslo modules in guest image

We now have dependencies on code that has graduated from oslo-incubator
to their own oslo modules. We need to make sure these are installed
on the trove guest image.

Specifically we need to now install:
oslo.i18n>=1.0.0
oslo.serialization>=1.0.0
oslo.utils>=1.0.0
oslo.messaging>=1.4.0
