[core] Adds #persisted? to Fog models

Fog models have been able to use #new_record? for years to use an
ActiveRecord like interface to check for peristence of a resource.

When Rails 3 switched to using ActiveModel API this changed to
be #persisted?

This deprecates #new_record? and adds #persisted? as the first little
step to making fog models easier to use using ActiveModel API.

As discussed on the tickes, ActiveModel is not planned to become a
direct dependency for fog.

Relates to #1276
[Brightbox] Deprecates incorrect form of #request

Whilst DRYing up the code we replaced the standard version of #request
with one that had clearer arguments and returned parsed data.

This was mostly fine but introduced a few problems:

* mock functionality expects the original interface
* headers returned in request are not available

This makes the newer version available as #wrapped_request and as a
deprecated form through #request.
[Brightbox] Replaces usage of deprecated #request

This removes the usage of the incorrect form of #request that was
introduced by mistake. It switches to use the #wrapped_request version
which has identical functionalit to the deprecated version.
[AWS] CopySnapshot. supports cross-region snapshot copying.
