No Auto-upgrade Chef Server and Manage (#4024)

* No Auto-upgrade Chef Server and Manage

Automatic upgrades do not automatically run chef-server-ctl upgrade or reconfigure.
This is not correct.

Chef Server/Manage repos should have `enabled=0` set and the person responsible for Chef Server will manually run the Chef Server/Manage upgrade.
