Replace manual 'wget' with puppet module

[jeff1evesque]

We will replace the manual exec implementation of wget, with the equivalent puppet module, when the wget::fetch syntax question has been resolved. Specifically, we should have an implementation as follows within install_drush.pp:

...
## include puppet modules
include wget

## variables
$drush_version = '8.0.0-rc4'

## download drush: wget is a wrapper around the 'exec' function
#
#  @timeout, override the default 'exec' timeout
#  @verbose, verbose logging
wget::fetch {'download-drush':
  source      => "https://github.com/drush-ops/drush/releases/download/${drush_version}/drush.phar",
  destination => '/tmp/drush.phar',
  verbose     => false,
}
...

This issue may be related with not including the following within install_drush.pp:

## define $PATH for all execs
Exec {path => ['/usr/bin/']}
...

This issue is invalid, since we are no longer implementing the wget package.
