Added support for setting up maintenance windows of under an hour.
Added support for using tokens instead of usernames and passwords.

Also added missing fields to documentation and added some more examples.
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.
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)"
       }

set type and default value
Fix parameters check for ec2_vol

Split the error check into two error checks and delay the
checks so that listing existing volumes works more nicely.

The error check should check that:
* One and only one of volume_size id or name is set

This fix adds the 'only one' part of that check and provides
more useful error messages.
