(MODULES-9668 ) Please make ProxyRequests setting in vhost.pp configurable

[aukesj]

This fork and change makes 'ProxyRequests' in Apache vhost sections managed by puppetlabs-apache configurable. I created a Jira ticket as well (MODULES-9668)

Thanks for your PR and filing of a bug against this module. Please address @ekohl and my feedback. Also I see a test for the default value set to false if we can test the true code path as well we can get this merged. Thanks again.

Premature approval. Still needs test for proxy set to true.

I ran the tests up to 'bundle exec rspec spec/acceptance' (which fails locally with these errors (12 times):

An error occurred while loading ./spec/acceptance/vhosts_spec.rb. Failure/Error: require 'beaker-rspec/spec_helper' RuntimeError: Failed to exec 'vagrant destroy --force'. Error was /usr/lib/ruby/2.5.0/rubygems.rb:289:in find_spec_for_exe': can't find gem vagrant (>= 0.a) with executable vagrant (Gem::GemNotFoundException)
from /usr/lib/ruby/2.5.0/rubygems.rb:308:in activate_bin_path' from /usr/local/bin/vagrant:23:in

'`

The Unit tests succeeded however (bundle exec rake spec):

Finished in 44 minutes 44 seconds (files took 3 minutes 8 seconds to load) 7439 examples, 0 failures

Furthermore, I'm using the fork succesfully with the option proxy_requests enabled.
