How to parameterize a Hashicorp's Nomad Job for user-defined variables?

Description

This sample Nomad job attempts to clone a github repository from a github account, and then perform ls command to verify if it downloaded.

However, the cool thing is, it uses parameterized construct to parameterize the repository name so I can re-use this nomad job to clone any repository at runtime.

Motivation for writing

# A Lookup plugin to lookup EC2 instance IDs with given Name tag

# The plugin accepts instance name, i.e. the value for Name tag
# and returns a list of Instance IDs with that Name tag

# USAGE:
# - debug: msg="{{ lookup('lookup_ec2', instance_name) }}"
# OR
# with_lookup_ec2: "{{ instance_name }}"
