> Because multiple KDCs may exist for an installation (failover, high availability, etc...),
Ambari should allow a user to specify multiple KDC hosts to be set while enabling Kerberos
and updating the Kerberos service's configuration.
> This should be done by allowing {{kerberos-env/kdc_host}} to accept a (comma-)delimited
list of hosts and then parsing that list properly when building the krb5.conf file where each
{{kdc_host}} item generates an entry in the relevant realm block.  For example:
> {noformat:title=kerberos-env}
> {
>   ...
>  "kdc_hosts" : "kdc1.example.com, kdc2.example.com"
>   ...
> }
> {noformat}
> {noformat:title=krb5.conf}
> [realms]
>   EXAMPLE.COM = {
>     ...
>     kdc = kdc1.example.com
>     kdc = kdc2.example.com
>     ...
>   }
> {noformat}
