puppet_agent : could autodetect package_version based upon the compiling master

Module Version: 2.1.1
Puppet Version: N/A
OS Name/Version: N/A

package_version must be explicitly specified, but could be based upon the version of the compiling master.

This would allow users to specify that agent version matches the version on the master without having to manually update package_version after upgrading the master(s).

class {'puppet_agent':

  package_version => 'master',

}

Notes:

'auto' could be used instead of 'master' as a keyword.

This is a POC.
