Serratus CLI front-end wrapper script

[ababaian]

Currently to get serratus up and running requires a few steps including building containers, uploading them, initializing AWS credentials and access keys, then submitting a job (sraRunInfo table) to the scheduler via curl. This is detailed in the Readme.md

• Create a wrapper script for Serratus such that you can type in serratus --sra <runInfo.csv> and it will go through the launch procedures and begin processing data.

• Create a build script for Serratus such that you can type in serratus --build and it will make the AMI via packer, make containers if they don't exist and create all the neccesary resources files for serratus.

This should be implemented in POSIX-complient bash.
