OSTF tests can not use third-party keystone

[Svetlana Shturm]

There is opportunity in Fuel create new plugin.
It can use third-party keystone.
OSTF tests use default keystone endpoint, that can be different with origin.
Right now we can modify only user name and password for OSTF tests.
In this specific case we need in modification of auth_uri.

Looks like it is BP instead of bug.

    Use service_endpoint as endpoint for environment

    To enable granular deployment of keystone, we need to know
    precisely where keystone will be configured, as we dont have
    such API in nailgun, we need to invent some convention.

    Important to remember that we also need proxy on port 8888 configured
    on a node that consumes configured vip.
