Description

Since it's now possible to specify principal and keytab for Kerberos configuration in Kafka processors (0.10 and 0.11), it'd be useful to enable EL to ease template promotion between environments when users are relying on variable registry.

I know there are on-going developments to provide a way to externalize Kerberos configuration in a controller service object but, in the meantime, enabling EL on the properties could be appreciated.
