beorn7 767c0709b1 Retrieval: Avoid copying Target
retreival.Target contains a mutex. It was copied in the Targets()
call. This potentially can wreak a lot of havoc.

It might even have caused the issues reported as #2266 and #2262 .

Julius Volz f92532f254 api: Consolidate web API contexts
This is based on the common/route changes in
https://github.com/prometheus/common/pull/61.

Julius Volz c187308366 storage: Contextify storage interfaces.
This is based on https://github.com/prometheus/prometheus/pull/1997.

This adds contexts to the relevant Storage methods and already passes
PromQL's new per-query context into the storage's query methods.
The immediate motivation supporting multi-tenancy in Frankenstein, but
this could also be used by Prometheus's normal local storage to support
cancellations and timeouts at some point.

Julius Volz ed5a0f0abe promql: Allow per-query contexts.
For Weaveworks' Frankenstein, we need to support multitenancy. In
Frankenstein, we initially solved this without modifying the promql
package at all: we constructed a new promql.Engine for every
query and injected a storage implementation into that engine which would
be primed to only collect data for a given user.

This is problematic to upstream, however. Prometheus assumes that there
is only one engine: the query concurrency gate is part of the engine,
and the engine contains one central cancellable context to shut down all
queries. Also, creating a new engine for every query seems like overkill.

Thus, we want to be able to pass per-query contexts into a single engine.

This change gets rid of the promql.Engine's built-in base context and
allows passing in a per-query context instead. Central cancellation of
all queries is still possible by deriving all passed-in contexts from
one central one, but this is now the responsibility of the caller. The
central query context is now created in main() and passed into the
relevant components (web handler / API, rule manager).

In a next step, the per-query context would have to be passed to the
storage implementation, so that the storage can implement multi-tenancy
or other features based on the contextual information.

Julius Volz 0c1e7a5b00 Support time range in /api/v1/series endpoint.
This adds optional "start" and "end" form values that may be used to
restrict the time range of returned series.

Jonathan Boulle 38098f8c95 Add missing license headers
Prometheus is Apache 2 licensed, and most source files have the
appropriate copyright license header, but some were missing it without
apparent reason. Correct that by adding it.
