If `get_all_instances` returns multiple reservations, the old wait loop only
dealt with the first reservation. Thus, the wait loop may end before all
instances get to be running/stopped.

Also clean up the code a little.

Modified Cron to add AIX Crontab support

from mpdehaan and redone entirely.

Include changelog from previous release.

update changelog, these weren't major features so move to other section

Shared module docs for remaining rax modules

add distribution_major_version to fact gathering

Allow vault encrypted vars as extra_vars

cloudformation's disable_rollback must be a bool

passing "yes" to boto causes severe problems.

Update apt:deb with correct version

The docs site says this option is available in 1.5, but it is not.  

#5910 https://github.com/ansible/ansible/pull/5910 added the deb option.  The PR was generated two months ago (before 1.5) but was not included until after 1.5 was released.  This fixes the docs.

ec2_snapshot: fix for "unknown type number requested for wait_timeout"

apt_key: Output URL for debugging

Also added a new integration test for assemble using local assembly
with a delimiter.

This builds on GH-6359 and changes the logic so that a newline is only inserted between fragments if the previous fragment does not end with a newline.

* Catch issues with invalid regions
* Ensure we send string only data as meta values in the rax module
* Add public_key/lookup example for rax_keypair
* Clean up import statements

Add version_compare filter

rax.py inventory script improvements

Expose the playbook to callback plugins

Use common file argument system previously implemented by @sivel for rax modules on the file modules as well (copy/file/template).
Application to other cloud providers would make very good sense.

Fixes #6842

ssh: propagate prompt to _communicate()
