Hey @pnp/cli-for-microsoft-365-maintainers, here's a proposed implementation for simplifying working with SharePoint URLs in SPO commands. Few noteworthy choices:

• the feature works based on a whitelist of options. If the particular option is not in the whitelist, the URL specified in its value won't be expanded
• each command can exclude a specific option from the whitelist if it needs that option to keep the server-relative URL (check the PR for a few examples)
• if SPO URL is not known to the CLI, and one of the option uses a server-relative URL, CLI will return an error prompting the user to either use an absolute URL or specify the SPO URL using the spo set command

I've also updated our test scripts to avoid repetition and allow running coverage tests without linting to speed up dev process.

Looking forward to hearing what you think
