This bug was exposed while running updated functional tests

If USER_PROXY is not set, the rocci/*.sh tests can run with token

Distinct with a directory structure
Create curl functional tests

Allow admins to declare which methods they like to disable.
Also, group common storage funcs to run from one place.

When a new key is registered, it is registered on req.environ in a
dict called 'soi:public_keys'.
The snf_create_server method pulls the keys from there and handles
the way they are injected into the VM.

When launching a new docker container, the user can now set the
repo branch to be deployed. Defaults to "develop".

Rename "paste_deploy/" to "ci/" and add a Dockerfile to create an
image which runs the snf-occi service.
Write instructions in ci/README.md on how to build and run the
container.
Update the docs and fix emerging bugs and typos.

Dockerfile version is now 0.3
