Issue BAM-11250: Improve AMI customisation process and documentation 
We need to run through the entire customisation process for both Linux and Windows and update the documentation to reflect the process. If we can write any scripts (and host them on bitbucket) that can improve EC2 customisation, we should do this. Currently its difficult to find out what version of bamboo-elastic-image you need - is it safe to always use the latest? How can the customer find this out? Please try the process out using the Ubuntu LTS to see if we can shake out any problems we do not see on CENTOS/Fedora
