Is your enhancement related to a problem? Please describe.

Task of this epic #15046
To support tracing with self manager Jaeger, we need che-operator to be able to install Jaeger.

Describe the solution you'd like

Update CheCluster CRD with:

tracing:
  jaeger:
    enable: # default true

If true and Jaeger CRD is defined in the cluster, create Jaeger CR:

apiVersion: jaegertracing.io/v1
kind: Jaeger
metadata:
  name: che-jaeger
  labels:
    app: che
    component: jaeger
