[#52201683] Added vagrant support for new puppetmaster node

Puppet Master refers to modulepath and manifestpath
(https://github.gds/gds/puppet/blob/master/modules/puppet/templates/etc/puppet/puppet.conf.erb#L16)
Hence mounting additional folders for Puppet Masters to run with their
normal production-like configurations.
