Ign pkg_create

[harshmahesheka]

🎉 New feature

Depends on https://github.com/gazebosim/gz-cmake/pull/262

Summary

This pull request is regarding my GSoC project which you can visit here . The idea is to create an ignition subcommand that can create a template ignition package based on the user's demands. You can see currently supported options here. Currently in the advanced package option a sample world, model, executable and plugin is made with code to install it.

Would love everyone's review on how to shape it better for users!

Test it

Build this repo with its dependencies and run ign pkg_create --help to see various options.

Also, https://raw.githubusercontent.com/ignition-tooling/gazebodistro/master/collection-fortress.yaml has gz packages names instead of ign.I am confused, shouldn't fortress have ign name?
