##### SUMMARY

When I run `ansible-galaxy [type] init`, I would like to be able to use my own configured 'skeleton' to init that content.

For Ansible roles, when running `ansible-galaxy role init myrole`, I can configure a [`GALAXY_ROLE_SKELETON`](https://docs.ansible.com/ansible/latest/reference_appendices/config.html#galaxy-role-skeleton) in my `ansible.cfg`, and the init command will use that skeleton as the source for the new role.

For Ansible collections, currently there's a bug (https://github.com/ansible/ansible/issues/66255) that causes collections to use that skeleton if its set (which can lead to some confusion)—but once that bug's fixed, there's no way to specify a skeleton for a collection.

So this feature request is to add a new configuration option `GALAXY_COLLECTION_SKELETON` (environment variable `ANSIBLE_GALAXY_COLLECTION_SKELETON`) which allows a collection skeleton to be specified.

Note: the docs for `GALAXY_ROLE_SKELETON` currently state:

> Role or collection skeleton directory to use as a template for the `init` action in `ansible-galaxy`, same as `--role-skeleton`.

Therefore that would need adjusting too, if the previously mentioned bug doesn't fix that.
