Inconsistent naming convention with Ozone Kerberos configuration

In SetupSecureOzone.md, the naming convention for keytab files are different from code.

hdds.scm.http.kerberos.keytab
ozone.om.http.kerberos.keytab

In ozone-default.xml, it is looking for:

hdds.scm.http.kerberos.keytab
ozone.om.http.kerberos.keytab.file

For the non http version of keytab, they are branded as:

hdds.scm.kerberos.keytab.file
ozone.om.kerberos.keytab.file

It is best to shorten the name to remove .file suffix from the code to be consistent with Hadoop naming convention. The second nitpick is hdds and ozone prefix. Is there a good reason to have distinct prefix for both that work closely together? How about hadoop.ozone prefix? From usability point of view, the current prefix are very confusing.
