Add an ec2-linux osfamily option
Improve datadir fuctionality

Initally when the datadir option is set it would only create the data dir but not set it in the config.
This improvement will allow it to be created ( a single dir or an array of dirs ) and also set this in the config file

Update init scripts and templatize

Updated the naming so we can add an instance name to them.

At the moment we use stdlib 3.2.0 which doesn't have the suffix function.
Merging it in manually now in the module solves this for now.
