Switch to unarchive module

[edwinkortman]

Using this module sends out a warning. This PR will fix that warning by switching to the ansible unarchive module instead of executing a tar command.

[WARNING]: Consider using the unarchive module rather than running tar.  If
you need to use command because unarchive is insufficient you can add
warn=False to this command task or set command_warnings=False in ansible.cfg to
get rid of this message.

This does not work I think? The unarchive module assumes the archive to be on the host, not on the guest

This also does not work with the currect destination path. I'm working on it...

The following line worked on my local test:
unarchive: remote_src=true src=/tmp/beanstalkd-{{ beanstalkd_version }}.tar.gz dest=/tmp

Thanks! Tested it as well and it works now. :)
