Add support for tags parameter to cloudformation module

Expose boto.cloudformation.create_stack() tags parameter. Supplied tags
will be applied to stack and all it's resources on stack creation.
Cannot be updated later (not supported by UpdateStack CloudFormation
API).
Added a new check to check whether an network interface is in promiscuous mode
Added an space between code and comments in order to follow the coding standars
apt: pass child process stdout and stdout to m.fail_json() and m.exit_json().

Without this, this fails:

    - name: apt-get dist-upgrade
      action: apt upgrade=dist
      register: apt_get_contents

    - name: apt-get clean
      action: command apt-get clean
      when: apt_get_contents.stdout.find("0 upgraded") == -1

TASK: [apt-get clean] *********************************************************

fatal: [192.168.2.2] => error while evaluating conditional: {% if apt_get_contents.stdout.find("0 upgraded") == -1 %} True {% else %} False {% endif %}

FATAL: all hosts have already failed -- aborting
apt: do not consider not-removed and not-upgraded packages as changes.

If one pins a package and does a 'apt-get dist-upgrade' then the
output looks like:

    # apt-get dist-upgrade
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    Calculating upgrade... Done
    The following packages have been kept back:
      cassandra
    0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

The check for any changes made should only be on the 'upgraded' and
'newly installed' values and not include the 'to remove' and 'not
upgraded' values.
Add Boto version check for tags parameter of cloudformation module

Tags parameter requires at least version 2.6.0 of Boto module. When tags
parameter is used with older version, error is raised. When tags
parameter is unused, module works as before.
Add version_added to cloudformation tags parameter
Fix check for ROLLBACK_COMPLETE in cloudformation module

When stack creation is rolled back, final status is not
CREATE_ROLLBACK_COMPLETE but ROLLBACK_COMPLETE.
Enforce umask for cron module, so cron_file generated files are 0644.

Certain cron implementations get cranky if files in cron.* are group
writable.
Add AWS ElastiCache module
initial ejabberd_user module
Module for swdepot (HP-UX package manager)
Made some code cleanups and use of module.run_command
Change file swdepot perms
Changed ansible target version
Added resp= option for svr4pkg to enable the -r option in pkgadd for response files
Add pager support to ansible-doc

If PAGER is set, or the executable less is present, ansible-doc will use
it to pipe information into so that it can be scrolled through.
If the environment variable LESS is not set, this will set it to FRSX.
