Install omniout_crowd with gitlab via puppet

gistfile1.pp

  file_line { 'omniauth_crowd-gem':
    path    => '/opt/gitlab/embedded/service/gitlab-rails/Gemfile',
    line    => 'gem "omniauth_crowd", "2.2.2"',
    require => Package['gitlab']
  }

  file_line { 'patch-devise-rb':
    path    => '/opt/gitlab/embedded/service/gitlab-rails/config/initializers/devise.rb',
    line    => "      provider_arguments << provider['args'].symbolize_keys",
    match   => "^      provider_arguments << provider\\['args'\\]\$",
    require => Package['gitlab']
  }

  exec { "install-omniouth-crowd-gem":
    unless  => '/bin/sh -c "test -d /opt/gitlab/embedded/service/gem/ruby/2.1.0/gems/omniauth_crowd-2.2.2"',
    cwd     => '/opt/gitlab/embedded/service/gitlab-rails',
    command => '/opt/gitlab/embedded/bin/bundle install',
    require => [ File_Line['omniauth_crowd-gem'], File_Line['patch-devise-rb'] ],
    before  => [ Exec['/usr/bin/gitlab-ctl reconfigure'], Exec['start gitlab'] ]
  }

This was hugely helpful. Thanks for putting this out there.

One thing to note:
Line 10 doesn't work for me until I change it to this:

    match   => "^.*provider_arguments << provider\[\'args\'\]",

please update the gem version to 2.2.3. For the new installation 7.11 and newer the 2.2.2 will not work.
