Move code out of schema.resolvers.go because it's not linted

[omarkohl]

The file cleosrv/graph/schema.resolvers.go seems to be detected as auto-generated even though that is only partially true. golangci-lint automatically skips generated files and seems to give no recourse in this case (see https://github.com/golangci/golangci-lint/issues/2864).

In addition some linters also impose restrictions e.g. gci has a skip-generated: true option which defaults to true.

The easiest solution for this is to ensure that the file contains as little code as possible and just calls external functions or methods in a path more clearly under our control.
