Can't fetch repos using 'git' protocol

[Andrey Sledzinskiy]

Steps:
1. Clone fuel-ccp and install requirements
2. Fetch repos using git protocol:
ccp --repositories-path $(pwd)/microservices-repos --repositories-protocol git --repositories-hostname git.openstack.org --repositories-port 9418 fetch

Expected - repos are fetched

Actual - cloning failed because of '@' before 'hostname'
Failed to fetch: 'git clone -v git://@git.openstack.org:9418/openstack/fuel-ccp-stacklight /home/asledzinskiy/Work/tmp/fuel-ccp/microservices-repos/fuel-ccp-stacklight' returned with exit code 128
fatal: unable to connect to @git.openstack.org

So it seems that our tool isn't implied to use 'git' protocol that is 'no authentication' protocol.
We should fix it or remove 'git' from options

    Move repository URL generation down to fetch_repository

    We can't use config interpolation from oslo.config once we remove it and
    it won't solve this bug anyway because its template is static, so we
    should solve it where url is being used instead.
