ec2api service is initialized with no workers count which leads to only
one worker is run.
ec2api_workers configuration settings will be used to set workers
count.

This code introduces standalone service which proxies its calls to
existing nova EC2-API.
All the code here except for the ec2api/api/proxy.py,
ec2api/api/ec2client.py and some util functions is taken from current
nova and unused functionality is cut of it.
The proxy.py and ec2client.py files implement the new code which
proxies incoming request (on port 8788) to original EC2 API in nova
on port 8773.
The result is transparently translated back to user.
