```

When remove read is enabled, federation will call `q.Select(nil, mset...)`
which will break remote reads because it currently doesn't handle empty
SelectParams.

* config: set target group source index during unmarshalling

Fixes issue #4214 where the scrape pool is unnecessarily reloaded for a
config reload where the config hasn't changed.  Previously, the discovery
manager changed the static config after loading which caused the in-memory

Brian Brazil 78efdc6d6b
Avoid infinite loop on duplicate NaN values. (#4275)
Fixes #4254

NaNs don't equal themselves, so a duplicate NaN would
always hit the break statement and never get popped.

We should not be returning multiple data point for the same
timestamp, so don't compare values at all.

Thomas Jackson 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).
