swift3(s3) works like ec2-api.
1. swift3/ec2-api recieves AWS request
2. it parses signature and access_key (and other headers)
3. it sends these values (and token that calculated from request) to keystone
4. keystone gets secret_key from DB, then calculates signature by
recieved access_key and token
5. keystone compares recived signature and claculated signature and
then return 'error' or auth_token
6. swift3/ec2-api recieves answer from keystone and return 'forbidden'
or continues execution
7. in case of continue swift3/ec2-api uses recieved auth_token for
calls other services: nova, cinder, neutron, swift...
So I don't understand how implement this functionality outside of keystone...
