Allows the Kafka client to be configured using the TLS registry

[cescoffier]

Description

Allows the Kafka client to be configured with the TLS registry (for the TLS aspect of it).

Basically, when kafka.tls-configuration-name is set, we need to locate the TLS configuration from the registry and set:

security.protocol=SSL
ssl.truststore.location=/var/private/ssl/kafka.client.truststore.jks  
ssl.truststore.password=test1234. # Trust store password
ssl.keystore.location=/var/private/ssl/kafka.client.keystore.jks  
ssl.keystore.password=test1234 # Key store password
ssl.key.password=test1234 # Alias password

Unfortunately, the KAfka configuration only accepts files. This means we would need to extract these files from the configuration and cannot use the already processed KeyStore instances.
