Refactor remote-exec inline code into scripts

[jamierajewski]

The terraform remote-exec blocks are getting quite messy - it would be preferable to:

• Move them to script(s)
• Copy the scripts using the file provisioner
• Running them with remote-exec's inline mode and passing terraform variables as command-line options
• At the end, remove these scripts from the instances

A better alternative - using cloud-init and templates to fill in the IPs. Example here.
