feat: add public flag to marketplace list

[pmarchini]

What this PR is for?

This PR adds the --public flag to marketplace list command in order to allow users to retrieve public marketplace items.

I'm not thoroughly convinced on the mechanics of the flag.

If I'm listing marketplace items for a company I think that I'm expecting to see all marketplace items for that company, publics and privates. Can it be that the flag will work in reverse? Like by default the value is true and the user must set it to false to see only private elements. Or mutate it to --hide-public. Can it be done via our API as they exists now?

Regarding this:

At the moment the marketplace list command shows only private marketplace items related to a specific company (--company-id), what we want to add it's a flag that allows the user to retrieve elements from public marketplace.
We're going to change the behavior in order to show only public elements while ´--public´ flag is being set. *

EDIT:

We have defined the following behavior for our command line options:

• --company-id: This flag is mandatory and retains its current behavior.
• --public: When this option is used, the command output will additionally include publicly available marketplace items.
