Julius Volz ac203ef0ee Add externalURL template function (#2716)
This allows users to e.g. add links back to the generating Prometheus
right in their alert templates.

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.

beorn7 75bae065fd Revert "Modify tests to adjust to reverting the /graph changes"
This reverts commit f1ea5bf232.

Part two necessary for reverting the /graph revert.

beorn7 f1ea5bf232 Modify tests to adjust to reverting the /graph changes
These tests have been added after the /graph changes and therefore
already test the new syntax.

This commit has to be reverted together with the previous one to get
back to the old new state. *sigh*

beorn7 4b574e8a61 Switch chunk encoding to type 2 where it was hardcoded type 1 before
The chunk encoding was hardcoded there because it mostly doesn't
matter what encoding is chosen in that test. Since type 1 is
battle-hardened enough, I'm switching to type 2 here so that we can
catch unexpected problems as a byproduct. My expectation is that the
chunk encoding doesn't matter anyway, as said, but then "unexpected
problems" contains the word "unexpected".
