Add Rackspace Cloud DNS Resource

This will be a temporary solution to have a resource for DNS until
Designate is incubated. Also currently work is in progress for a
new API for Designate.
Until then this will serve as a resource for Rackspace Cloud DNS.

Make check_uptodate compatible with BSD shells

BSD mktemp requires a template for the file/directory name.
GNU mktemp supports the option, but is not mandatory.

This change passes in the template, so that the check_uptodate.sh is
more compatible across different environments.
