Delete lib/puppet/rest* and related tests. We no longer use that code for cert related REST calls.
The Puppet::SSL::Host class needs to be deleted first (in PUP-10252).
deprecation warning exists in lib/puppet/rest/routes.rb, which is the entry point to all this code.
This needs to be removed before we remove the deprecated SSL code. (or at the same time)
Merged to main in https://github.com/puppetlabs/puppet/commit/0baaba6576e012ee1e96259f99dd4bcfc73e65f0
