[auth] Add logic to store and retrieve auth tokens

[jcastill]

This commit implements functionality to store and
retrieve authorization tokens obtained remotely from a
distribution-defined authentication portal. This
enables users to reuse previously obtained tokens
that remain valid, eliminating the need to request a new token for each subsequent interaction.

@pmoravec @arif-ali I'd be very grateful if you can start the review of this PR. I'll move it out of draft after RH QE finish their review as well

[jcastill]

And new version, this time removing the old or faulty token file. I think I've covered all cases where we should remove it, but let me know if I missed any

[pmoravec]

Just those minor issues spot, LGTM otherwise.

[pmoravec]

I wasnt sure if the Draft status means you plan to further change something, hence no ACK given. Assuming the PR is complete, ACK to it.
