Dan Prince 43af5e45c7 Add noauth middleware
This patch implements noauth middleware that can be enabled by
adding the following to heat.conf:

[paste_deploy]
flavor = noauth

One use case for this middleware would be to use alongside of a single
process heat-all setup (using fake_rpc, sqlite) to avoid having to
bootstrap keystone to use only the Heat software deployments resources.
We could use this approach to help bootstrap TripleO's undercloud using
heat templates with pre-deployed servers (a single undercloud server
for the intial case).
