> Add (optional) {{master_kdcs}} to {{kerberos-env}} and generated krb5.conf file. If {{kerberos-env/master_kdcs}}
is not empty, it should contain a list of IP addresses or FQDNs for one or more KDCs. Multiple
entries should be comma-delimited.
> According to https://web.mit.edu/kerberos/krb5-1.12/doc/admin/conf_files/krb5_conf.html:
> {quote} 
> master_kdc
> Identifies the master KDC(s). Currently, this tag is used in only one case: If an attempt
to get credentials fails because of an invalid password, the client software will attempt
to contact the master KDC, in case the user’s password has just been changed, and the updated
database has not been propagated to the slave servers yet.
> {quote}
> This should help with scenarios where multiple KDCs are in a master/slave (or replicated)
configuration.
