Provide verbose details about which galaxy server was used

[AlanCoding]

SUMMARY

This adds debug messages so that people can ascertain the source for the requirements they are using. As far as I can tell, there's no other output telling the user what the correspondence is.

COMPONENT NAME

lib/ansible/galaxy/collection.py

ADDITIONAL INFORMATION

I'm building examples for such cases:

https://github.com/AlanCoding/collection-requirements-cases

Here is the output for a case that makes use of @chrismeyersfsu https://galaxy.ansible.com/chrismeyersfsu/test_things, which is not available on https://galaxy-dev.ansible.com. It first tries galaxy-dev, and gets a 404. It then installs from the release galaxy. These debugging statements make that traceable.

[AlanCoding]

actually, we would prefer 3 v's because

https://github.com/ansible/awx/blob/43d816b6e4c7ea01c31e42e713101cf51011b534/awx/main/tasks.py#L1887

[jborean93]

It would be good to also add the URL used to this and the other message you've added below. The name isn't that useful for people who are relying on the defaults and seeing the URL as well helps them to understand what was actually used. An example is https://github.com/ansible/ansible/blob/devel/lib/ansible/galaxy/collection.py#L435

[AlanCoding]

yeah, formatting (collection , api.name, api.api_server) looks good to me

[AlanCoding]

With latest update, output looks like this:

I agree, that is a nice aesthetic.
