The 'profile' variable notably induces dracut to be excruciatingly slow,
mitigate chance by putting confluent before apikey, mgr, and profile.
Further, it has been requested to have the scripts use same name on
server for directory moving forward. Implement this request while
allowing existing OS profiles to keep working.
After going through tmp and etc, settle on /etc/confluent/
as the generally relevant directory when possible.
Additionally, move apikey and ifidx logic into apiclient where
possible
