Create an Ubuntu 14.04 based LogSearch Workspace that runs in Vagrant and EC2

This PR creates:

A (remote) Ubuntu 14.04 based LogSearch Workspace containing all the configuration, source code and dependancies for for operating and developing a LogSearch cluster.

Using this workspace you can easily:

* Launch a test LogSearch cluster (in a local Vagrant VM or a remote EC2 VM)
* Deploy and administer a production multi-VM LogSearch cluster - using configuration as code
* Develop and customise the LogSearch components and make your own LogSearch release

It does not attempt to provide a solution for editing the files in the workspace.

To get started, 

```
git clone https://github.com/logsearch/workspace ~/logsearch-workspace
cd ~/logsearch-workspace
git checkout checkout-source-into-virtual-workspace
vagrant up
```

And then follow the documentation at: https://github.com/logsearch/workspace/tree/checkout-source-into-virtual-workspace#single-user-local-vagrant-vm - starting from step 3
