Fabian Reinartz 1ede7b9d72 Consolidate TargetStatus into Target.
This commit simplifies the TargetHealth type and moves the target
status into the target itself. This also removes a race where error
and last scrape time could have been out of sync.

Fabian Reinartz 0d7105abee Remove scrape config from Target.
This commit removes the scrapeConfig entirely from Target.
All identity defining parameters are thus immutable now and the mutex
can be removed..

Target identity is now correctly defined by the labels and the full URL.
This in particular includes URL parameters that are not specified in the
label set.

Fingerprint is also removed from hash to remove an unnecessary tight coupling
to the common/model package.

Fabian Reinartz 75681b691a Extract HTTP client from Target.
The HTTP client is the same across all targets with the same
scrape configuration. Thus, this commit moves it into the scrape
pool.

Fabian Reinartz 1a3253e8ed Make scrape time unambigious.
This commit changes the scraper interface to accept a timestamp
so the reported timestamp by the caller and the timestamp
attached to samples does not differ.

Fabian Reinartz fe7e91e2eb Make scraping offset consistent.
To evenly distribute scraping load we currently rely on random
jittering. This commit hashes over the target's identity and calculates
a consistent offset. This also ensures that scrape intervals
are constantly spaced between config/target changes.

Rework the way to communicate backpressure (AKA suspended ingestion)

beorn7 ec08c9a391 Rework the way to communicate backpressure (AKA suspended ingestion)
This gives up on the idea to communicate throuh the Append() call (by
either not returning as it is now or returning an error as
suggested/explored elsewhere). Here I have added a Throttled() call,
which has the advantage that it can be called before a whole _batch_
of Append()'s. Scrapes will happen completely or not at all. Same for
rule group evaluations. That's a highly desired behavior (as discussed
elsewhere). The code is even simpler now as the whole ingestion buffer
could be removed.

Logging of throttled mode has been streamlined and will create at most
one message per minute.

beorn7 a7408bfb47 Unify duration parsing
It's actually happening in several places (and for flags, we use the
standard Go time.Duration...). This at least reduces all our
home-grown parsing to one place (in model).

Brian Brazil 50258929ac Retrieval: Show error message for failed test scrape
This is flaky, and I suspect it was due the to I/O timeout that I've
already fixed. In case that wasn't it, display the error should it
happen again.

Brian Brazil 93145b960a retrieval: Reduce flakiness of target tests
Bump timeouts of tests where we don't want I/O timeouts.

Adjust the full channel test to be much more reliable,
by reducing the ingestion timeout from 1ms to 0.

Julius Volz f63a899744 Change config regexes to full-string matches.
This anchors all regular expressions entered via the config to match a
full string vs. a substring.

THIS IS A BREAKING CHANGE!

Julius Volz 963ad82dcb Fix "go vet" errors.
I ignored all errors of the type "composite literal uses unkeyed
fields". Most of them are wrong because of
https://github.com/golang/go/issues/9171.

Will Rouesnel 7810448dbe Add proxy_url parameter to allow specifying per-job HTTP proxy servers
Allow scrape_configs to have an optional proxy_url option which specifies
a proxy to be used for all connections to hosts in that config.

Internally this modifies the various client functions to take a *url.URL pointer
which currently must point to an HTTP proxy (but has been left open-ended to
allow the url format to be extended to support others, such as maybe SOCKS if
needed).

Brian Brazil d8875d17d8 Retrieval: Make it possible to relabel query params

Fabian Reinartz dc7d27ab9a retrieval: add honor label handling and parametrized querying.
This commit adds the honor_labels and params arguments to the scrape
config. This allows to specify query parameters used by the scrapers
and handling scraped labels with precedence.

Brian Brazil 0dbae36d36 Allow ingested metrics to be relabeled.
The main purpose of this is to allow for blacklisting
of expensive metrics as a tactical option.
It could also find uses for renaming and removing labels
from federation.

Brian Brazil 58ceae82bc Revert "Allow ingested metrics to be relabeled."
This reverts commit f2f26ca08f.

Was accidentally pushed to master instead of a branch for PR.

Fabian Reinartz 8de50619f1 Increase target test wait times

Fabian Reinartz 385919a65a Avoid inter-component blocking if ingestion/scraping blocks.
Appending to the storage can block for a long time. Timing out
scrapes can also cause longer blocks. This commit avoids that those
blocks affect other compnents than the target itself.
Also the Target interface was removed.

Fabian Reinartz 1a2d57b45c Move template functionality out of target.
The target implementation and interface contain methods only serving a
specific purpose of the templates. They were moved to the template
as they operate on more fundamental target data.
