Puppet master plugin breaks hiera call

During testing of plugin which deploys puppet master it was discovered that a hiera call (in check_deploy_state method) "hiera roles" fails with error:

2016-04-11 15:03:11,343 - ERROR utils.py:494 -- Unexpected exit_code returned: actual 1, expected 0. Command: 'hiera roles node-3.test.domain.local' Details: {'host': '10.109.0.5', 'command': 'hiera roles node-3.test.domain.local', 'exit_code': 1, 'stderr': ["/usr/lib/ruby/vendor_ruby/hiera/backend/nailgun_backend.rb:77:in `lookup': Failed to lookup node in nailgun (RuntimeError)\n", "\tfrom /usr/lib/ruby/vendor_ruby/hiera/backend.rb:174:in `block in lookup'\n", "\tfrom /usr/lib/ruby/vendor_ruby/hiera/backend.rb:171:in `each'\n", "\tfrom /usr/lib/ruby/vendor_ruby/hiera/backend.rb:171:in `lookup'\n", "\tfrom /usr/lib/ruby/vendor_ruby/hiera.rb:60:in `lookup'\n", "\tfrom /usr/bin/hiera:221:in `<main>'\n"], 'stdout': []}

For this case fqdn parameter should be provided to hiera call, e.g.:
hiera roles fqdn=node-3.test.domain.local

This is fixed in the following patchset:
