Notes
keytab option doesn't exist in any wrapper libs. env var getting used directly by C lib https://web.mit.edu/kerberos/krb5-1.11
Add support for a "default client keytab". Its location is determined by the KRB5_CLIENT_KTNAME environment variable, the default_client_keytab profile relation, or a hardcoded path (TBD).
