Peer Service Mapping per host, name and base-path

[mmorel-35]

Is your feature request related to a problem? Please describe.
On a service if I have

• service A on localhost:8001
• service B-V1 on localhost:8002/api/v1
• service B-V2 on localhost:8002/api/v2
• service C on mycompany.org

The otel.instrumentation.common.peer-service-mapping property is unable to map the services correctly

Describe the solution you'd like
The first thing is that I would to be able to map a service based on host and port.
And if possible also per base path so I can provide something like

otel.instrumentation.common.peer-service-mapping=localhost:8001=service-a,localhost:8002/api/v1=service-b-v1,localhost:8002/api/v2=service-b-v2,mycompany.org=service-c
