This feature is to allow users to set up the custom preset with a tag that tells bootstrap to resolve the public IP or hostname of an ec2 node automatically.
Something like:
nodes: - host: {{ec2PublicIP}}
nodes: - host: {{ec2PublicHostanme}}
By calling the current ec2 instance meta-data:
curl http://169.254.169.254/latest/meta-data/public-ipv4 curl http://169.254.169.254/latest/meta-data/public-hostname
There are some nuances. The instance should have metadata v1 enabled. With metadata v2, it is more secure. SO, you'll need to get a token first.

We could add similar helper functions for other cloud providers.
