* Enabling validation-modules for rackspace modules

* Removed test in rax.py

* Added markup to items in list

* rax_monm_check.py: moved choices doc to description for check_type

As the argument_spec does not contain the "choices" spec, adjusting that in the docs

* rax_monm_check.py: a number of things missing in docs, fixed

(cherry picked from commit af4474efd7)
