In histogram_quantile merge buckets with equivalent le values (#5158) 
This makes things generally more resilient, and will
help with OpenMetrics transitions (and inconsistencies).

9a956872a3 Make ErrorStorage a concrete type not an interface 
Since it is used in a type assertion, having it as an alias to the
error interface is the same as saying 'error', i.e. it succeeds for
all types of error.  Change to a struct which is a concrete type and
the type assertion will only succeed if the type is identical.

* 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.
