Expose the playbook to callback plugins
Require a recent enough version of pycrypto and see that playbook and vault ues it.
distutils' requires parameter doesn't work with setuptools.  Use
setuptools' instal_requires instead
Allow vault encrypted vars as extra_vars

Forward the vault_password to the yaml file utility.

Improvements to the rax inventory script
Treat 255 errors from raw as dark host

Any other module is able to detect a dark host, but raw was treating 255
as a return code from the module execution, rather from the connection
attempt. This change allows 255 to be treated as a connection failure
when using the raw module.
Allow you to pass in arbitrary rsync options. I also added help for it, and what version it was added in.
Allow raw and script to support su
ssh: Properly check for wrong su password
ssh: propagate prompt to _communicate()

_communicate() uses the prompt variable to detect wrong passwords early,
therefore it needs to be passed to it from exec_command().
ssh connection plugin: Report missing sudo password

If no password is provided, sudo hangs at the prompt. Identify this and
report that the password is missing as an error.

Make `vpc_security_group` docs more accurate

Without the `subnet` parameter supplied there's an error `msg: Parameter vpc_security_groups invalid for create command`. (This might be a bug?)

If the VPC security group name rather than ID is supplied there's an error: `msg: Invalid security group , groupId= <some group name>, groupName=.` (Accepting a group name might be a feature enhancement.)

In my case I set the subnet as `default` and used `register` to get the result of the security group creation section and just referred to its `group_id` property.
