oslo.messaging 1.5.0 causing issues for cinder, sahara,heat (stable/juno)

[Adam Gandelman]

I believe this is hitting master branches as well, but we cannot merge a requirements update to stable/juno which removes unwanted caps on oslo libraries . Cinder's relies on fake_rabbit which was removed, and other updates are causing config samples to go stale. This can be addressed properly with patches to those project's master branches, but the stable/branches should stay functional with older version of the libraries and config samples there should remain relevant to those compatable versions.

sahara (stale config): https://review.openstack.org/#/c/138861/
cinder (broken tests, stale config): https://review.openstack.org/#/c/138855/
heat (stale config): https://review.openstack.org/#/c/138857/

I pushed https://review.openstack.org/138963 to unblock stable/juno before 2014.2.1 release today.

    Reintroduces fake_rabbit config option

    This change reintroduces the fake_rabbit only for backward compatibility,
    but mark it as deprecated.

    Now, to use the kombu in-memory driver (that is not thread safe) we must
    set the transport_url config option to 'kombu+memory:////" or the
    rpc_backend to kombu+memory.

    Or we can use the fake driver of oslo.messaging by setting the
    transport_url to 'fake:///' or the rpc_backend to 'fake'

    This is effectively reverting commit bcb3b23b8f6e7d01e38fdc031982558711bb7586.

Thanks for the quick 1.5.1 release, I pulled the breaks on https://review.openstack.org/138963
let's see if that will stop Zuul from merging it.

ok, breaks released on https://review.openstack.org/138963 because 1.5.1 did not help in Juno, config/check_uptodate.sh fails due to changes in cfg parameters
