Print values unquoted in apply dependency template.

[n00by]

Remove quotes from values in template. This makes it possible to use variables as value, e.g.

icinga2::object::apply_dependency { 'vm-host-to-parent-master': parent_host_name => 'host.vars.vm_parent', ... }

To use a string as value, set quotes in the config, e.g.

icinga2::object::apply_dependency { 'vm-host-to-internet': parent_host_name => '"core-router"', ... }
