* Move availability_zone docs to each OpenStack module
This argument is in the central list for hysterical raisins (mostly me
being a doofus) but is used in almost none of them. Document it
explicitly in each module to stop the confusion.
* Fix two docs formatting bugs
* Update validate-modules
* Validates ANSIBLE_METADATA
* Ensures imports happen after documentation vars
* Some pep8 cleanup
* Clean up some left over unneeded code
* Update modules for new module guidelines and validate-modules checks
* Update imports for ec2_vpc_route_table and ec2_vpc_nat_gateway
The shade update_router() call will return None if the router is
not actually updated. This will cause the module to fail if we
do not protect against that.
The exception message, when shade fails, will contain much more
specific information about the failure if the exception is treated
as a string. The 'message' attribute alone is usually not helpful.
Allow the 'interfaces' attribute to represent internal router
interfaces, composed of subnet names, and the 'external_fixed_ips'
attribute to represent external interface subnet/IP.
