There's many places in the convert2rhel code where we refer to GPG key fingerprints while in fact we use/store/compare GPG key IDs.

A GPG key ID is either short or long

• Long: the last 16 hex characters (64 bits) of the fingerprint
• Short: the last 8 hex characters (32 bits) of the fingerprint

On some places we work with long, on others with short IDs. We have a ticket to unify that to the long format: RHELC-959.

Acceptance criteria:

• All the code/config files where we refer to fingerprints but in fact we work with key IDs have the comments/function names/variable names/class attributes reworded to not use the word fingerprint
