The staticcheck warns about testing.T usage in goroutines. Moving the
t.Fatal* calls to the main thread showed immediately that this is a good
practice, as one of the test setups didn't work.
* Fixed int64 overflow for timestamp in v1/api parseDuration and parseTime
This led to unexpected results on wrong query with "(...)&start=148966367200.372&end=1489667272.372"
That query is wrong because of `start > end` but actually internal int64 overflow caused start to be something around MinInt64 (huge negative value) and was passing validation.
BTW: Not sure if negative timestamp makes sense even.. But model.Earliest is actually MinInt64, can someone explain me why?

Expose buildQueryUrl, refactor dispatch to use
buildQueryUrl will allow users to execute queries over the range of an
existing graph. This will be helpful to select data series they wish to
annotate the graph with, for example.
We need to be able to modify the HTTP POST in Weave Cortex to add
multitenancy information to a notification. Since we only really need a
special header in the end, the other option would be to just allow
passing in headers to the notifier. But swapping out the whole Doer is
more general and allows others to swap out the network-talky bits of the
notifier for their own use. Doing this via contexts here wouldn't work
well, due to the decoupled flow of data in the notifier.
There was no existing interface containing the ctxhttp.Post() or
ctxhttp.Do() methods, so I settled on just using Do() as a swappable
function directly (and with a more minimal signature than Post).
The automatic GZIP handling of net/http does not preserve
buffers across requests and thus generates a lot of garbage.
We handle GZIP ourselves to circumvent this.t
Each remote write endpoint gets its own set of relabeling rules.
This is based on the (yet-to-be-merged)
https://github.com/prometheus/prometheus/pull/2419, which removes legacy
remote write implementations.
