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

+# vCenter cluster testbed automation
+
+## Overview
+
+This directory contains scripts to automate VCSA/ESXi install and cluster configuration for developing and testing.
+
+## Dependencies
+
+### govc
+
+Install the latest release via https://github.com/vmware/govmomi/releases
+
+### jq
+
+Used here to derive static VCSA networking from its parent ESXi host.
+But, you should already be using and loving jq for other tasks: http://stedolan.github.io/jq/
+
+## Scripts
+
+### create-esxi-vm.sh
+
+This script creates a VM running stateless ESXi, booted via cdrom/iso.
+It will create 2 disks by default:
+
+* vSAN cache disk (Virtual SSD)
+
+* vSAN store disk
+
+The two vSAN disks will be unformatted, leaving them to be autoclaimed
+by a vSAN enabled cluster.
+
+Note that for a cluster to use vSAN, it will need at least 3 of these
+ESXi VMs.
+
+To create an ESXi VM for standalone use, use the `-s` flag and optionally increase the default disk size with the `-d`
+flag:
+
+```
+./create-esxi-vm.sh -s -d 56 $GOVC_URL my-esxi-vm
+```
+
+The script can also be used directly against Workstation.  Without a username in the url, govc will use local ticket
+authentication.  No password is used in this case, but the script will still use this value to set the password for
+`root` in the ESX vm.  You may also want to decrease the default disk `-d` and memory `-m` sizes.  Example:
+
+```
+GOVC_NETWORK=NAT ./create-esxi-vm.sh -d 16 -m 4 -s :password-for-esx60@localhost $USER-esxbox
+```
+
+For use against Fusion, use `.` as the hostname:
+
+```
+./create-esxi-vm.sh -d 16 -m 4 -s root:password-for-esx60@. $USER-esxbox
+```
+
+### create-vcsa-vm.sh
+
+This script creates a VM with VCSA (Virtual Center Server Appliance) installed.
+
+### create-cluster.sh
+
+The first argument to the script is the IP address of VCSA.
+There must be at least three arguments that follow, IP addresses of ESXi hosts, to form the cluster.
+
+The script then creates the following managed objects:
+
+* Datacenter (dc1)
+
+* ClusterComputeResource (cluster1)
+
+* DistributedVirtualSwitch (DSwitch)
+
+* DistributedVirtualPortgroup (PublicNetwork)
+
+* DistributedVirtualPortgroup (InternalNetwork)
+
+All of the given host systems are:
+
+* Added to the ClusterComputeResource (cluster1)
+
+* Added to the DistributedVirtualSwitch (DSwitch)
+
+* Enabled for vSAN traffic (vmk0)
+
+* Firewall configured to enable the remoteSerialPort rule
+
+Cluster configuration includes:
+
+* DRS enabled
+
+* vSAN autoclaim of host system disks (results in shared Datastore "vsanDatastore")
+
+## Example
+
+This example will install VCSA, 3 ESXi VMs and create a cluster.
+
+```
+export GOVC_URL="root:password@some-esx-host"
+
+./create-vcsa-vm.sh -n "${USER}-vcsa" $GOVC_URL
+
+printf "${USER}-esxi-%03d\n" {1..3} | xargs -P3 -n1 ./create-esxi-vm.sh $GOVC_URL
+
+govc vm.ip -k "${USER}-vcsa" "${USER}-esxi-*" | xargs ./create-cluster.sh
+```
+
+## Licenses
+
+Optional, if you want to assign licenses to VCSA or ESXi hosts.
+
+Where "ESX_LICENSE" should be that of "vSphere 6 per CPU, Enterprise Plus".
+
+And "VCSA_LICENSE" should be that of "vCenter Server 6, Standard".
+
+```
+ESX_LICENSE=... VCSA_LICENSE=... ./assign-licenses.sh
+```
