## 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.

## Description
Adds a server-side filter that removes all
personal (aka: oneDrive) sites from the drive
retrieval.
The approach is not my preferred method. I'd rather
have used a filter in the query parameters. In fact, I
have a functioning query in postman:
`$filter=NOT contains(webUrl, 'sharepoint.com/personal/')`
But I can't seem to get the graph client query to build
when I add that to the query params.

## Description
Adds a lookup for all tenant site ids when a new
graph connector is created. Also adds an enum
to flag which resource set (users, sites, or all)
that the connector should initialize.
