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.

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.

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.

Introduces support for the new metadata endpoint from Prometheus. The new endpoint provides information independent of targets and collapses the unique combinations of HELP, TYPE and UNIT.
Fixes#705

The part after the underscore has to be lowercase. Otherwise, it is
seen as the name of a Go type, which doesn't exist, which will result
in the example not showing up in godoc.

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.
