[CDAP-21096] Split Appfabric into stateless service and stateful processor

[vsethi09]

Context

Make appfabric service stateless by splitting it into appfabric service to server HTTP requests and appfabric processor to run subscriber services and process message.

Change Description

• Upgrade from Golang 1.19 to 1.23 since:

  • Golang version 1.19 is out of support and version 1.23 is the latest available version.
  • Tests were failing as controller-runtime/tools/setup-envtest@latest is compatible with golang version 1.19.
  • Note: go.sum was generated by running go mod tidy.

• CDAP master types:

  • Added new config for AppFabricProcessor of type AppFabricProcessorSpec. AppFabricProcessorSpec consists of stateful spec CDAPStatefulServiceSpec.
  • Changed spec for AppFabricSpec to stateless spec CDAPScalableServiceSpec.

• deployment.go:

  • Changed type of appfabric service as k8s deployment.
  • Added appfabric processor of type k8s statefulset.

• Auto-generated files:

  • api/v1alpha1/zz_generated.deepcopy.go
  • CRD: config/crd/bases/cdap.cdap.io_cdapmasters.yaml

Verification

1. Tested using unit tests in golang by running make test.
2. Deployed locally built cdap-operator image to a k8s cluster and verified by deployed CRD and CR.
