Eugene Nikanorov 9f4e3a7107 Avoid loading policy when processing rpc requests
When Neutron server is restarted in the environment where multiple agents
are sending rpc requests to Neutron, it causes loading of policy.json
before API extensions are loaded. That causes different policy check
failures later on.
This patch avoids loading policy when creating a Context in rpc layer.
