storage: add openstack_storage_url option

[elthariel]

In order to support ACL management in my provider (OVH), I need to have users in a different tenant and I need to use another base URL for my storage calls. In the python client it is implemented using the OS_STORAGE_URL.

This is the equivalent option for fog.

I don't really know how to add tests to this, suggestions are highly welcomed

This looks good. Just a question, see above conversation. Regarding tests, since you have the module utils you should be able to easily unit test #management_url. For a good explanation and example check out https://chriskottom.com/blog/2015/03/testing-ruby-mixins-in-isolation/

@ShamoX seems reasonable to me and should be backwards compatible, thoughts?

[ShamoX]

Yes, seems good, but adding a test like @gildub proposed would improve confidence.

@elthariel still need help here to do it (even after @gildub proposition) ?
