Moves out node pool manager behind an extension using runner pool abstraction (Part 2) (#862)

Browse Source 
* Move out node-pool manager and replace it with RunnerPool extension

* adds extension points for runner pools in load-balanced mode

* adds error to return values in RunnerPool and Runner interfaces

* Implements runner pool contract with context-aware shutdown

* fixes issue with range

* fixes tests to use runner abstraction

* adds empty test file as a workaround for build requiring go source files in top-level package

* removes flappy timeout test

* update docs to reflect runner pool setup

* refactors system tests to use runner abstraction

* removes poolmanager

* moves runner interfaces from models to api/runnerpool package

* Adds a second runner to pool docs example

* explicitly check for request spillover to second runner in test

* moves runner pool package name for system tests

* renames runner pool pointer variable for consistency

* pass model json to runner

* automatically cast to http.ResponseWriter in load-balanced call case

* allow overriding of server RunnerPool via a programmatic ServerOption

* fixes return type of ResponseWriter in test

* move Placer interface to runnerpool package

* moves hash-based placer out of open source project

* removes siphash from Gopkg.lock

SipHash (Go)
============
[![Build Status](https://travis-ci.org/dchest/siphash.svg)](https://travis-ci.org/dchest/siphash)
Go implementation of SipHash-2-4, a fast short-input PRF created by
Jean-Philippe Aumasson and Daniel J. Bernstein (http://131002.net/siphash/).
## Installation
$ go get github.com/dchest/siphash
## Usage
import "github.com/dchest/siphash"
There are two ways to use this package.
The slower one is to use the standard hash.Hash64 interface:
h := siphash.New(key)
h.Write([]byte("Hello"))
sum := h.Sum(nil) // returns 8-byte []byte
or
sum64 := h.Sum64() // returns uint64
The faster one is to use Hash() function, which takes two uint64 parts of
16-byte key and a byte slice, and returns uint64 hash:
sum64 := siphash.Hash(key0, key1, []byte("Hello"))
The keys and output are little-endian.
## Functions
### func Hash(k0, k1 uint64, p []byte) uint64
Hash returns the 64-bit SipHash-2-4 of the given byte slice with two
64-bit parts of 128-bit key: k0 and k1.
### func Hash128(k0, k1 uint64, p []byte) (uint64, uint64)
Hash128 returns the 128-bit SipHash-2-4 of the given byte slice with two
64-bit parts of 128-bit key: k0 and k1.
Note that 128-bit SipHash is considered experimental by SipHash authors at this time.
### func New(key []byte) hash.Hash64
New returns a new hash.Hash64 computing SipHash-2-4 with 16-byte key.
### func New128(key []byte) hash.Hash
New128 returns a new hash.Hash computing SipHash-2-4 with 16-byte key and 16-byte output.
Note that 16-byte output is considered experimental by SipHash authors at this time.
