Resolves #78 Script to automate EC2

[rcarterjr]

This script implements the initial features requested. The script requires three arguments in order:

1. URL for Accumuo git repo and a branch in that repo
2. URL for Accumuo testing repo and a branch in that repo
3. Local dir where muchos is setup.

I will continue working on this and adding the long term goals.

@rcarterjr what's the status of this PR? It looks OK maybe just needs someone to test it out on a cluster?

[rcarterjr]

This script now takes the args.txt as its only argument with the following inputs on their own line in the following order:

• accumulo git repository
• accumulo branch
• accumuluo-testing git repository
• accumulo-testing branch
• fluo-muchos git repository
• fluo-muchos branch
• path/to/muchos.props

I will work on creating environment variables instead of having the text file and iterating through as discussed.

@milleruntime @keith-turner here are my latest changes. Let me know what you think.

[milleruntime]

Nice improvements. Just a couple minor things and then I think we can merge it.

[milleruntime]

I will merge this up but we can continue to test and make improvements.

It would be nice to have a quick mention in the readme with a pointer to a readme in it directory that describes how it use it.

@rcarterjr as another follow on task, you could run ShellCheck on the script: https://github.com/koalaman/shellcheck.

Thanks Mike, that's a neat tool.

And I will write up a readme now Keith.

And I will write up a readme now Keith.

When you do that I will try to follow the readme and run this thing. So far I have only reviewed the code script, I have not tried to run it.
