[KOGITO-165] - Kogito Runtime Services integration with Infinispan

See:
https://issues.jboss.org/browse/KOGITO-165

In this PR:

1. Introduced the possibility to deploy Infinispan
2. New spec added to KogitoApp: Infra.InstallInfinispan. Always means that the operator should always install a Infinispan instance; Never won't install, even if requires - the user will provision and configure their own installation; Auto will try to figure out scanning image metadata

The only problem I saw is that if the service doesn't set the infinispan properties in the application.properties, won't work since Quarkus is not reading from env. See a working example here: https://github.com/ricardozanini/kogito-examples/blob/infinispan-props/onboarding-example/onboarding/src/main/resources/application.properties#L4-L6

@mswiderski is this a problem? We can set the -D in the images if the envs where found in the container. For Quarkus:

  - env:
            - name: NAMESPACE
              value: kogito
            - name: KOGITO_DATAINDEX_URL
            - name: QUARKUS_INFINISPAN_CLIENT_SERVER_LIST
              value: 'kogito-infinispan:11222'
            - name: QUARKUS_INFINISPAN_CLIENT_AUTH_USERNAME
              value: developer
            - name: QUARKUS_INFINISPAN_CLIENT_AUTH_PASSWORD
              value: Z1Nz34JpuVdzMQKi
            - name: QUARKUS_INFINISPAN_CLIENT_SASL_MECHANISM
              value: PLAIN

@mswiderski one more thing, the onboarding example is failing (I just deployed the onboarding, not the others services): https://pastebin.com/AHXuMRPu. Fixed, to work all three services must be running.

Is this the expected behavior? Tomorrow I'll try to deploy the other services.

And of course the payroll and hr services also have to be deployed.

Regarding the requirement of having properties set in the application.properties file:
quarkusio/quarkus#5708

[radtriste]

code seems ok to me. I am going to test a bit :)

[ricardozanini]

@xiezhang7 @spolti could you guys please review? I intend to merge this by Monday EOD to start working on others JIRAs that depend on this one. Many thanks!

[ricardozanini]

@radtriste as soon as you finish your tests, please report back so we can decide if should be merged.

Seems good to me.
Tested with CLI and CR file.

CLI command used (for onboarding service):
kogito deploy-service onboarding-service https://github.com/kiegroup/kogito-examples/ --context-dir=onboarding-example/onboarding --install-infinispan=Always --incremental-build --build-env MAVEN_ARGS_APPEND=-Ppersistence -e NAMESPACE=kogito-165
