Fixup for SuSE and openSuSE.

Account for differences in packages names across RHEL/CentOS
and SuSE/openSuSE.
If an AWS account does not have a default subnet in their VPC configuration, then creating instances in that VPC will not automatically provide a public IP/DNS. Boto added this functionality in 2.13.0 (NetworkInterfaceSpecification.associate_public_ip_address).

This change adds assign_pubic_ip as a parameter to the ec2 module, ensuring that it is not set to one of BOOLEANS_TRUE if vpc_subnet_id is not also set, and if Boto is less than 2.13.0.
Exit 0 with no matched hosts

And also print to stdout not err

This lines up with how ansible-playbook will exit. 0 in the case of no
matched hosts. This makes it easier to script ansible commands w/
variable iventory input which may or may not have an entry for the
specific ansible task being scripted. No matched hosts is acceptable,
but matched hosts w/ failures is not.

openbsd_pkg: rework package name parsing.

Give the module more knowledge of the package name structure.
This makes the handling of version-less flavors (like vim--no_x11)
behave properly.

While here sprinkle debug logging that is helpful when testing the
module.
compatible with python 2.4
Fix for RPM build on opensuse

Opensuse (tested on 12.3) doesn't have package 'python2-devel', just
python-devel. This patch sort this and allow build RPM successfully
on OpenSuse 12.3.
Add ansible.module_utils.rax
Nova doesn't attempt to auth on obj instantiation

Need to call nova.authenticate() to validate credentials.
Improved documentation of `mount` module

Mentioning the fact that mount point directories are created and
removed.
Added promote command to promote read-replicas to standalone databases (http://aws.amazon.com/about-aws/whats-new/2012/10/11/amazon-rds-mysql-rr-promotion/).  Added ability for the modify command to rename a database instance via the optional new_instance_name parameter
Fixed hostname module for RHEL6 Workstation
Fix for documentation playbook loops

if key is used with lookup parameter that needs to be in quotes as
otherwise it will load "ssh-rsa" "<the key>" "<the comment>" as separate
values and fail with "this module requires key=value arguments"
Added support for parsing in the SLES patch level correctly

On SLES, the setup module was returning the architecture as the distribution version (i.e. platform.dist() didn't quite return the right thing). This change checks for /etc/SuSE-release and grabs the second column in the third line as distribution_version.
