prepare plugins needs to happen so registration can occur to build the plugin args (#2119)

* prepare plugins needs to happen so registration can occur to build the plugin args

use yaml.dump

include dataset and more assertions

* attempt to manually register plugins rather than use fn

* fix fixture

* remove fixture

* move cli test to patched dir

* fix cce validation
