* Removed modules no longer have documentation
Decided this was causing people to think that modules were supported
even after being removed. This change is a new strategy to have the
error message trying to use a removed module point people to the older
documentation.
* Add stubs for modules removed in 2.7
These are freshly removed so we want people who are still using them
when they upgrade Ansible to have a hint as to where to find information
on how to port.
* Finish properly undeprecating include
include was undeprecated earlier but not all of the pieces that marked
it as deprecated were reverted. This change fixes the remaining
pieces
