Thomas Jackson 0392dffd0e
Switch to POST for LabelNames, Series, and QueryExemplars to DoGetFallback (#1252)
The upstream prometheus HTTP API supports POSTS for these methods (the
same as Query and QueryRange). Similar to the original issue
(https://github.com/prometheus/client_golang/issues/428) we can hit 414
errors with these other APIs. This change simply duplicates the logic to
these other endpoints

beorn7 2236d782ff api: Extend and improve json-iterator usage
For one, this pulls up the histogram-related json-iterator usage from
prometheus/common into the API client. Previously, the only
json-iterater usage was here in the API client. But then json-iterator
was used for the native histogram additions directly in
prometheus/common, see
https://github.com/prometheus/common/pull/440/files . This however
meant that any user of prometheus/common/model would now link in
json-iterator, even if they are not using the JSON marshaling at
all. To keep prometheus/common/model more leightweight, this commit
moves all the json-iterator usage into the API client itself, as it
was done before for the normal float samples.

This commit also adds an unmarshaling function for native histograms,
which didn't even exist in prometheus/common/model so far.

It also adds json-iterator marshaling and un-marshaling for
model.SampleStream, which is only needed for the benchmark
(BenchmarkSamplesJsonSerialization). This fixes the benchmark such
that it actually compares json-iterator and std-lib json encoding
(which didn't work before because the custom marshaling methods of
model.SampleStream enforced std-lib json encoding for floats and
json-iterator encoding for histograms in all cases).

I expect this to fix #1179.

Łukasz Mierzwa dc1559e8ef
Update /api/v1/status/tsdb to include headStats (#925)
Current structs for v1 HTTP API assume that there is chunkCount and timeSeriesCount on /api/v1/status/runtimeinfo, which seems to be gone for at least a few releases. /api/v1/status/tsdb now holds an extra headStats block with chunkCount, numSeries and a few other fields.
Update API models and tests to reflect this change.

beorn7 64b4a9cf9d API client: Enable fallback on status code 501, too
When discussing #801, I remembered #794. While dealing with the
latter, I read the HTTP RFC, stumbling upon the following:

    When a request method is received
    that is unrecognized or not implemented by an origin server, the
    origin server SHOULD respond with the 501 (Not Implemented) status
    code.  When a request method is received that is known by an origin
    server but not allowed for the target resource, the origin server
    SHOULD respond with the 405 (Method Not Allowed) status code.

Concluding from that, it is possible that a server desiring a fallback
to GET will send a status code of 501. It is even preferred if that
server does not offer any resource to be used with the POST method.

Therefore, I think we should fallback to GET on a 501, too.
