Make sure kick.py can still parse Puppet files with newer Puppet releases

[trev]

Background

We are using the kick.py script we are using to push updates to the servers. That script parses manifests/monitoringserver.pp file in order to validate host names and groups. For that it uses Puppet's parser. However, it was written for an older version of Puppet and no longer works with the current versions, producing the following exception:

/Library/Ruby/Gems/2.0.0/gems/puppet-3.4.2/lib/puppet/parser.rb:2:in `<top (required)>': uninitialized constant Puppet (NameError)

from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:110:in `require'
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:110:in `rescue in require'
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:35:in `require'
from -:2:in `<main>'

Adding require puppet to the Ruby code we are running here changes the exception to the following:

/Library/Ruby/Gems/2.0.0/gems/puppet-3.4.2/lib/puppet/settings.rb:315:in `block in convert': Could not parse for environment production: Error converting value for param 'manifest': Error converting value for param 'manifestdir': Could not find value for $confdir (Puppet::Error)

What to change

Update the Ruby code executed from kick.py to support current Puppet versions.
