API client: make http reads more efficient ( #976 )
...
Replace `io.ReadAll` with `bytes.Buffer.ReadFrom`.
Both need to resize a buffer until they have finished reading;
the former increases by 1.25x each time while the latter uses 2x.
Also added a benchmark to demonstrate the benefit:

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!

api: creates versioned package for prometheus v1 api
...
This commit creates a new package to hold the prometheus
v1 API interface. This interface will contain all the funcionality
exposed by Prometheus v1 HTTP API.
The underlying http client is kept on the api package since it
may be reused across diferent API versions and also by the Alertmanager
api package (to come.)
