We need to pass all `deploy` arguments to `upgrade prepare/converge` commands, not just -e parameters. (See bug 1571437 for possible effects if some params are left out.) This is most important for network data, roles data, and any role count parameters, but prepare/converge commands inherit from deploy, so we should simply carry over all.
There's a gotcha that some parameters were deprecated -- the --ntp-server and all --*-scale parameters. These should be converted into environment files, see
https://bugzilla.redhat.com/show_bug.cgi?id=1571437#c7
The commands which should receive all `deploy` args:
update prepare
update converge
upgrade prepare
upgrade converge
ffwd-upgrade prepare
ffwd-upgrade converge
ceph-upgrade run
