The pb package was only referenced in cmd/influx/query.go, but in
dead code, since it uses the same machinery as the repl, which goes
through the HTTP endpoints, rather than the gRPC endpoints.
We reorganized the functions in flux to have the structure:
/functions
/inputs
/transformations
/outputs
this PR catches up platform to work with the new package layout.
As a separate refactoring issue, we should discuss:
from(bucket: ) should migrate from flux --> platform
to_http and to_kafka should migrate from platform --> flux
It was effectively a copied and pasted platform.ID, so change it to a
type alias. Once our known references to the query/id package are
updated to platform.ID, we'll delete the package.
