Add Granular Services Counts to Telemetry

[AlexFenlon]

Proposed changes

This change granulaises the counting of services so instead of a total number, this adds a count for each service
eg. ClusterIP, LoadBalancer, NodePort and ExternalName.

I have added go tests for this functionality.

kubectl get services -A
