Fixed style issues, bundle install check now more specific

Quoted some attribute values in resources, and added the $ruby_vers to the
filename we touch when bundle install completes successfully. This will force
bundle install to run when the Ruby version has been changed.
Modified the default values for conf_agent

It was not necessary to use more than one hash for multiple roles, as the default
values were the same. Also removed some unnecessary keys from the hash.
Fixed resource dependency issue

The ruby-augeas gem needs the augeas-devel package to be installed prior
to its installation.
Added parameter for ruby-augeas gem

Added $augeas_vers parameter to allow for version control. Default value set to
'present'.
Enforced CRL check in Puppet Master vhost file

If Apache is >= 2.4, CRL checks won't happen unless "SSLCARevocationCheck 	chain"
is added. Also changed the default value for SSLVerifyClient from "optional" to
"require".
Updated Gemfile & Gemfile.lock
Improved unit & acceptance testing
Updated README.md
