[APM] Link to service via host.name, process.id and @timestamp

[sorenlouv]

Depended on by: #84849

Given only host.name, process.pid, @timestamp it should be possible to link to a service.

The following route:
/app/apm/link-to/service?host=my-host&pid=my-pid&timestamp=12345678

Should redirect to:
/app/apm/my-java-service/overview
