Install elasticsearch using enrollment tokens

I have not installed elasticsearch using rpm/tarball in a super long time since I use my deploy-elastic.sh script to install elasticsearch onto docker containers.

You can add allow_restricted_indices to the role to enable it back however its the lazy and insecure method.
