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

This simply removes the vendored deps that are no longer part of the

404abe0f1c Bubble up errors to promql from populating iterators (#4136) 
This changes the Walk/Inspect API inside the promql package to bubble
up errors. This is done by having the inspector return an error (instead
of a bool) and then bubbling that up in the Walk. This way if any error
is encountered in the Walk() the walk will stop and return the error.
This avoids issues where errors from the Querier where being ignored
(causing incorrect promql evaluation).
