Add packer template and documentation to generate VMware OVAs
Added a packer template to generate lab VM on VMware using Ubuntu 16.04 as base. Made minor changes to bootstrap.sh to accomodate more recent Ubuntu release including installing extra packages required for Ubuntu 16.04 and to skip update of grub menu.lst, which no longer exists. Added preseed.cfg file to create sudo-enabled ubuntu account required for lab. Added README.md to document usage and edited top-level README.md to refer to VMware as well as AWS.

# Building Rubber-Docker Workshop VMs
2+
3+
## Overview
4+
5+
This directory has two packer.json files that you can use to construct
6+
VMs for the lab. You'll need to [download
7+
packer](https://www.packer.io/downloads.html) or [build it from
8+
source](https://www.packer.io/docs/install/index.html#compiling-from-source).
9+
10+
Login using ubuntu/ubuntu for both VMs.
11+
12+
## AWS AMI
13+
14+
Set your AWS credentials as environmental variables and fill in a valid
15+
subnet ID from your VPC in rubber-docker-aws.json, then execute:
16+
```
17+
packer build rubber-docker-aws.json
18+
```
19+
Note that the source AMI is not accessible outside the region given
20+
in the packer build file.
21+
22+
## VMware OVA
23+
24+
Build on Mac OS X. In addition to packer you'll need VMware Fusion
25+
and ovftool. Execute the following:
26+
27+
```
28+
packer build rubber-docker-vmware.json
29+
ovftool packer-rubber-docker-ubuntu-16.04-vmware/rubber-docker-ubuntu-16.04.vmx rubber-docker-ubuntu-16.04.ova
30+
```
31+
The OVA is optional. You can also just start the VM directly in
32+
VMware Fusion.
33+
34+
Note: The external network interface name on the VM may switch from
35+
ens33 to ens32 when you export to ovftool and boot. If this occurs
36+
edit /etc/network/interfaces and switch the interface name to the
37+
correct value.
38+
39+
## Licensing
40+
41+
