gotjosh 7f509dc4f4 API Client: Support new metadata endpoint in v1 
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

beorn7 b8308329f0 Fix function names in API examples 
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.

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.

Related to #614

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!

Bob Shannon 18d13eacc9 Add support for fetching rules with API client (#508) 
This PR adds support for fetching [rules](https://prometheus.io/docs/prometheus/latest/querying/api/#rules) via the `/api/v1/rules` endpoint using the API client. Currently, the API client exposes no way to do this and it would be nice to have for external systems that wish to retrieve this information.

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

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

The underlying http client is kept on the api package since it

api package (to come.)
