[jaeger] Add Service Performance Monitoring

[ricoberger]

It is now possible to view the Jaeger Metrics for Service Performance Monitoring within kobs.

Service Performance Monitoring allows users to view the latency, error rate and request rate for all operation of a service. It is also possible to switch from the monitor view directly to the corresponding traces view of a selected operation.

• I adjusted the corresponding documentation for this change.
• I adjusted the values.yaml file and the documentation for all values.
