VMware vSphere Integrated Containers provider (#206)

* Add Virtual Kubelet provider for VIC

Initial virtual kubelet provider for VMware VIC.  This provider currently
handles creating and starting of a pod VM via the VIC portlayer and persona
server.  Image store handling via the VIC persona server.  This provider
currently requires the feature/wolfpack branch of VIC.

* Added pod stop and delete.  Also added node capacity.

Added the ability to stop and delete pod VMs via VIC.  Also retrieve
node capacity information from the VCH.

* Cleanup and readme file

Some file clean up and added a Readme.md markdown file for the VIC
provider.

* Cleaned up errors, added function comments, moved operation code

1. Cleaned up error handling.  Set standard for creating errors.
2. Added method prototype comments for all interface functions.
3. Moved PodCreator, PodStarter, PodStopper, and PodDeleter to a new folder.

* Add mocking code and unit tests for podcache, podcreator, and podstarter

Used the unit test framework used in VIC to handle assertions in the provider's
unit test.  Mocking code generated using OSS project mockery, which is compatible
with the testify assertion framework.

* Vendored packages for the VIC provider

Requires feature/wolfpack branch of VIC and a few specific commit sha of
projects used within VIC.

* Implementation of POD Stopper and Deleter unit tests (#4)

* Updated files for initial PR

+# Denco [![Build Status](https://travis-ci.org/naoina/denco.png?branch=master)](https://travis-ci.org/naoina/denco)
+
+The fast and flexible HTTP request router for [Go](http://golang.org).
+
+Denco is based on Double-Array implementation of [Kocha-urlrouter](https://github.com/naoina/kocha-urlrouter).
+However, Denco is optimized and some features added.
+
+## Features
+
+* Fast (See [go-http-routing-benchmark](https://github.com/naoina/go-http-routing-benchmark))
+* [URL patterns](#url-patterns) (`/foo/:bar` and `/foo/*wildcard`)
+* Small (but enough) URL router API
+* HTTP request multiplexer like `http.ServeMux`
+
+## Installation
+
+    go get -u github.com/go-openapi/runtime/middleware/denco
+
+## Using as HTTP request multiplexer
+
+```go
+package main
+
+import (
+    "fmt"
+    "log"
+    "net/http"
+
+    "github.com/go-openapi/runtime/middleware/denco"
+)
+
+func Index(w http.ResponseWriter, r *http.Request, params denco.Params) {
+    fmt.Fprintf(w, "Welcome to Denco!\n")
+}
+
+func User(w http.ResponseWriter, r *http.Request, params denco.Params) {
+    fmt.Fprintf(w, "Hello %s!\n", params.Get("name"))
+}
+
+func main() {
+    mux := denco.NewMux()
+    handler, err := mux.Build([]denco.Handler{
+        mux.GET("/", Index),
+        mux.GET("/user/:name", User),
+        mux.POST("/user/:name", User),
+    })
+    if err != nil {
+        panic(err)
+    }
+    log.Fatal(http.ListenAndServe(":8080", handler))
+}
+```
+
+## Using as URL router
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/go-openapi/runtime/middleware/denco"
+)
+
+type route struct {
+	name string
+}
+
+func main() {
+	router := denco.New()
+	router.Build([]denco.Record{
+		{"/", &route{"root"}},
+		{"/user/:id", &route{"user"}},
+		{"/user/:name/:id", &route{"username"}},
+		{"/static/*filepath", &route{"static"}},
+	})
+
+	data, params, found := router.Lookup("/")
+	// print `&main.route{name:"root"}, denco.Params(nil), true`.
+	fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+
+	data, params, found = router.Lookup("/user/hoge")
+	// print `&main.route{name:"user"}, denco.Params{denco.Param{Name:"id", Value:"hoge"}}, true`.
+	fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+
+	data, params, found = router.Lookup("/user/hoge/7")
+	// print `&main.route{name:"username"}, denco.Params{denco.Param{Name:"name", Value:"hoge"}, denco.Param{Name:"id", Value:"7"}}, true`.
+	fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+
+	data, params, found = router.Lookup("/static/path/to/file")
+	// print `&main.route{name:"static"}, denco.Params{denco.Param{Name:"filepath", Value:"path/to/file"}}, true`.
+	fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+}
+```
+
+See [Godoc](http://godoc.org/github.com/go-openapi/runtime/middleware/denco) for more details.
+
+## Getting the value of path parameter
+
+You can get the value of path parameter by 2 ways.
+
+1. Using [`denco.Params.Get`](http://godoc.org/github.com/go-openapi/runtime/middleware/denco#Params.Get) method
+2. Find by loop
+
+```go
+package main
+
+import (
+    "fmt"
+
+    "github.com/go-openapi/runtime/middleware/denco"
+)
+
+func main() {
+    router := denco.New()
+    if err := router.Build([]denco.Record{
+        {"/user/:name/:id", "route1"},
+    }); err != nil {
+        panic(err)
+    }
+
+    // 1. Using denco.Params.Get method.
+    _, params, _ := router.Lookup("/user/alice/1")
+    name := params.Get("name")
+    if name != "" {
+        fmt.Printf("Hello %s.\n", name) // prints "Hello alice.".
+    }
+
+    // 2. Find by loop.
+    for _, param := range params {
+        if param.Name == "name" {
+            fmt.Printf("Hello %s.\n", name) // prints "Hello alice.".
+        }
+    }
+}
+```
+
+## URL patterns
+
+Denco's route matching strategy is "most nearly matching".
+
+When routes `/:name` and `/alice` have been built, URI `/alice` matches the route `/alice`, not `/:name`.
+Because URI `/alice` is more match with the route `/alice` than `/:name`.
+
+For more example, when routes below have been built:
+
+```
+/user/alice
+/user/:name
+/user/:name/:id
+/user/alice/:id
+/user/:id/bob
+```
+
+Routes matching are:
+
+```
+/user/alice      => "/user/alice" (no match with "/user/:name")
+/user/bob        => "/user/:name"
+/user/naoina/1   => "/user/:name/1"
+/user/alice/1    => "/user/alice/:id" (no match with "/user/:name/:id")
+/user/1/bob      => "/user/:id/bob"   (no match with "/user/:name/:id")
+/user/alice/bob  => "/user/alice/:id" (no match with "/user/:name/:id" and "/user/:id/bob")
+```
+
+## Limitation
+
+Denco has some limitations below.
+
+* Number of param records (such as `/:name`) must be less than 2^22
+* Number of elements of internal slice must be less than 2^22
+
+## Benchmarks
