SPD-417: add scanner and get resources from tokens

[lnauta]

This merge will add the ability to scan a token for

1. Availability: Is there a token in a view?
2. Add resource-dependent clients: start a client based on information in a token

In this way a user can "just scan for tokens and start a client" if needed, and extend to multiple clients based on resource requirements in the tokens.

@hailihu I had to do some code duplication and making a setup.sh for the env, and I don't like either. If you have suggestions to improve this, please let me know.

[hailihu]

Great new functionality! I suggest to generalize scripts instead of duplicating them, and move example to general examples folder.

[lnauta]

The requested changes have been implemented, unfortunately, GH made them "outdated" when I moved files around. So I cant confirm the changes have been done. Anyway, they have been done.

[hailihu]

Great work! Some minor comments.

[lnauta]

Done.
(let's see if this submission changes the state if the PR, its not clear to me)

What has been done? I don't see a new commit.

I approved the old 'outdated' changes, but this didnt do anything. I can't see the latest change request.

Sorry, I didn't submit the review yet, done now.
