Thomas Jackson 92c6f0c92e Add offset to selectParams (#4226)
* Add Start/End to SelectParams
* Make remote read use the new selectParams for start/end

This commit will continue sending the start/end time of the remote read
query as the overarching promql time and the specific range of data that
the query is intersted in receiving a response to is now part of the
ReadHints (upstream discussion in #4226).

* Remove unused vendored code

The genproto.sh script was updated, but the code wasn't regenerated.
This simply removes the vendored deps that are no longer part of the
codegen output.
