Making updates related to fog api changes.

If we try to use 'endpoint' or 'compute_url' it will just silently
default to dfw and never create anything in ord.

Changed instances of endpoint to rackspace_region to be consistent
with fog.

Note that a bit of the documentation refers to the :lon region, but
this is not useable without the ability to set the auth url. This
was addressed in https://github.com/mitchellh/vagrant-rackspace/pull/4
but that had a couple other changes as well.
Copies action_provision from vagrant-aws plugin.
Added rackconnect option to plugin that allows plugin to wait for RackConnect to complete before doing SSH provisioning.
updating to add compute_url functionality
omitting version control files from rsync. using .hgignore and .gitignore to further omit files from rsync. addresses #22
Makes makes pre-rsync chown recursive.
Vagrantfile for testing - no need to git ignore because it doesn't
contain actual credentials
