Add suexec support

[ekohl]

This adds the suexec_user_group parameter to vhost and introduces a class
apache::mod::suexec, which is included when the parameter is used.

Unit test failures:

  1) apache::vhost os-independent items attribute resources when suexec_user_group is specified should contain File[25-rspec.example.com.conf] with content =~ /^SuexecUserGroup nobody nogroup$/
     Failure/Error: it { should contain_file("25-#{title}.conf").with_content %r{^SuexecUserGroup nobody nogroup$} }
       expected that the catalogue would contain File[25-rspec.example.com.conf] with content set to /^SuexecUserGroup nobody nogroup$/ but it is set to "# ************************************\n# Vhost template in module puppetlabs-apache\n# Managed by Puppet\n# ************************************\n\n<VirtualHost *:84>\n  ServerName rspec.example.com\n\n  ## Vhost docroot\n  DocumentRoot \"/rspec/docroot\"\n\n\n\n  ## Directories, there should at least be a declaration for /rspec/docroot\n\n\n  <Directory \"/rspec/docroot\">\n    Options Indexes FollowSymLinks MultiViews\n    AllowOverride None\n    Order allow,deny\n    Allow from all\n  </Directory>\n\n  ## Load additional static includes\n\n\n  ## Logging\n  ErrorLog \"/var/log/apache2/rspec.example.com_error.log\"\n  ServerSignature Off\n  CustomLog \"/var/log/apache2/rspec.example.com_access.log\" combined\n\n\n\n\n  SuexecUserGroup nobody nogroup\n</VirtualHost>\n"

Argh. Should be fixed now.

Still an issue with Ruby 1.8.7/puppet 2.7

Failures:

1. apache::mod::php on a RedHat OS with alternative extensions should When you call a matcher in an example without a String, like this:
   specify { object.should matcher }
   or this:
   it { should matcher }
   RSpec expects the matcher to have a #description method. You should either
   add a String to the example this matcher is being used in, or give it a
   description method. Then you won't have to suffer this lengthy warning again.
   Failure/Error: it { should contain_file("php5.conf").with_content =~ /AddHandler php5-script .php .php5\n/ }
   NoMethodError:
   undefined method `matches?' for false:FalseClass

   ./spec/classes/mod/php_spec.rb:73

I wonder if that's related to my patch or just slipped in because of Travis CI breakage.

[underscorgan]

I'll run the tests locally and see what happens...

[underscorgan]

:sigh:

Looks like this is, indeed, an issue with travis.

Why was this important PR not merged?

[ekohl]

@mbrodala I'm not sure what you mean since it was merged.

[mbrodala]

@ekohl I'm sorry I was confused since I came from Jira where there's only the "Closed" notice and I didn't double check here.

[ekohl]

@mbrodala I can see how Jira would lead you to think that :)
