Tomáš Dohnálek 40e54a75a6 Refactor apiClientImpl.DoGetFallback
Make apiClientImpl.DoGetFallback more idiomatic and efficient:
 * Save result of args.Encode() operation as it might be used 2 times in
   the function and due to looping and sorting it might be heavy.
 * Follow line-of-sight practise and therefore simplify the code.

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.

Thomas Jackson c52580de2b Change all time formatting to UTC and off of time.RFC3339Nano
Prometheus has issues parsing RFC3339Nano timestamps if the year has more than 4 digits, in addition it is the second-pass parse attempt. Since this is a client library and the interface is a `time.Time` it makes sense that we pick the clearest simplest format-- so I propose we use the `model.Time` representation of time in our communications to prometheus. This (1) removes the issues with timezones in those queries going downstream and (2) completely works around this #614 issue as the parsing mechanism in prometheus can handle those times in this format.

Bjoern Rabenstein 1173d73405 Increase minimum required Go version to 1.9
This allows us to simplify a bunch of code while still supporting the
last four Go minor versions.

We have also run into minor annoyances a couple of times by now to
keep supporting 1.7 and 1.8.

It's time to pull the plug!

Bryan Boreham 8fbbc9bc6b Decode JSON body when Prometheus returns 400 to an api call
400 and 422 are documented error codes from Prometheus, so we should
attempt to parse the error returned for both of them.

Needed to change a test that was requiring the old behaviour - made it
use 500 instead of 400.
