* Dynamically retrieve aws_bastion_ami latest reference by querying AWS rather than hard coded * Dynamically retrieve the list of availability_zones instead of needing to have them hard coded * Limit availability zones to first 2, using slice extrapolation function * Replace the need for hardcoded variable "aws_cluster_ami" by the data provided by Terraform * Move ami choosing to vars, so people don't need to edit create infrastructure if they want another vendor image (as suggested by @atoms) * Make name of the data block agnostic of distribution, given there are more than one distribution supported * Add documentation about other distros being supported and what to change in which location to make these changes
