Issue Description:

Currently we implement Reliable Session with embedded Infinispan. However, in production, server-client model is recommended (especially in OpenShift cases) because

• Separate infinispan related concerns (e.g. persistent volume) from drools side
• Native compiled infinispan could be used in the future

Acceptance Criteria:

• Enable server-client setting
• "embedded" and "server-client" can be configured easily (will likely be measured with benchmark)
• Use testcontainers for server-client test
