On slow env services requiring connection to both Infinispan and Kafka (like Data index to Travel agency applications) aren't able to start in 30 seconds (default liveness timeout) and are repeatedly terminated. 

To tackel this issue currently `initialDelaySeconds` has been introduced in liveness probe as a part of KOGITO-3874. 

`initialDelaySeconds` has been implemented in place of `startup probe` because `startup probe` is introduced from version 1.18 beta but kogito operator have to support with 1.15~1.17. 

Once Kogito Operator has been upgraded to support 1.22, then we could pick this task.
