rename graph.Service to Servicer (#1787)

## Description

`graph.Service -> graph.Servicer`,  no other changes.

More compliant with golang naming standards,
and will allow us to eventually migrate the
Service struct out of connector and into graph.

## Type of change

- [x] 🐹 Trivial/Minor

## Issue(s)

* #1725
