docs: refresh view samples

[tswast]

These snippets are copied from snippets.py and refreshed
to include imports and client construction. Will follow up
with a PR to remove the redundant snippets once the docs
on cloud.google.com are updated.

I notice that the tests for these snippets have been skipped.
I believe that was due to a temporary rollout issue with
table update. If that actually is flakier than I thought, we
can more easily add retries or disable just updates in this
new structure.

Re: snippet-bot's comment

I guess you're moving samples under samples dir. The bot is warning because some region tags are referenced from the devsite doc. This will cause 404 errors on our devsite pages.

I think the correct course of action is to 1) duplicate the sample, 2) update devsite, then 3) remove the old tags.

Thanks @tmatsuo for looking. Yes, I am trying to move these samples. I'll try your suggested process.
