Fix for plan peadm::add_compiler over pcp transport (#356)

* Replace agent installation in add_compiler plan to use component_install subplan

* Attempt to fix error with failing Puppet run due to disconnect to with rbac api

* Update unit test for add_compiler_spec

* Clean up indentation in add_compiler_spec

* Clean up code comments in add_compiler plan

* Use primary_target instead for parameter for consistency

* Update DNS alt names when adding a compiler over PCP
