I'm going to put some thoughts down for this.

From this issue: elastic/beats#21019

• its merging in the next day or two so would be good to prep some feature file work and implementation as needed.

briefly:
the feature adds in new support, and leaves the old in place.
So we'll still want to test the enroll and unenroll as we are. but we can add in new feature tests for 'install' and 'uninstall' from the Agent side.
