Wishlist: Add swift3 middleware

[Alexey 'Fenuks' Rusetsky]

Many tools/libs can work with object storage through Amazon S3 api, which is implemented in openstack as Swift3 (https://github.com/openstack/swift3).
Would be great to have it in OSA, as currently there are not that many libs that can work with Swift directly. And it requires an account, that would have full access to openstack tenant, to store objects from application in a swift container.

    Add Swift3 middleware to openstack_services

    This change causes the repo building process to clone the swift3
    middleware repo so a swift3 wheel can be built.

I was able to port those patches onto 13.3.15 (Newton) and playbooks (repo-build and os-swift-install) ran without failures. Swift restated and is working as before.

But looks like in order to work with swift3 one requires ec2 credentials. Even though cli seem to support them, openstack (keystone I presume) does not. Running 'openstack ec2 credentials create' returns 'Could not find requested endpoint in Service Catalog.'

Another middleware might be required — https://github.com/openstack/ec2-api
Without it swift3 is unusable, even if operational.

    Correct swift3 repo variable names

    With I56cd63057cc771310b69c311d975e06f73c773f7 now merged,
    the correct variables need to be used to ensure that they
