Make pip dry run work better for the common case

This change allows the pip module to figure out if something needs to be done during
a dry run using 'pip freeze'. This is implemented for the most basic case: name,
version and state=(present|absent). In other cases it will fall back to the old
behavior.
EC2 inventory toggle to exclude/include RDS instances.
Do not filter out RDS instances by default or in INI file to avoid changing current behaviour.
Setup module: Additional facts when using ansible with Linux on System z

- Improved parsing of /proc/cpuinfo to take the specifics of Linux on
System z. ansible_processor and ansible_processor_cores are now
completed.
- Also improved virtualization facts in the same environment, parsing
the output of /usr/bin/lscpu to populate virtualization_type and
virtualization_role more precisely. If lscpu is not available, then
stick to the previous behavior.
ec2: ability to list existing volumes
Introduce an ansible_version dict as runner variable

  Given the version:
    "1.6 (ansible_version_var 14499e8bf3) last updated 2014/03/21 17:07:50 (GMT +200)"

  We get the special variable:
    "ansible_version": {
        "full": "1.6",
        "major": 1,
        "minor": 6,
        "revision": 0,
        "string": "1.6 (ansible_version_var 14499e8bf3) last updated 2014/03/21 17:07:50 (GMT +200)"
       }
