[FEAT]: Add a wait block to agent flows

[zandercreations]

What would you like to see?

It would be beneficial to add a wait block that would postpone the next block running.

use cases:

1. If an API call needs an extended allotted time to process.
2. Running a get request right after a post request and the get cant return because the post didn't complete in time.

The API blocks should be blocking in the agent flow, prevent this kind of behavior. Do you mean an arbitrary wait so that after the POST returns, maybe the endpoint called has some extra processing time to do whatever it needs to do, then we can call the next?

I can imagine in some cases a POST would return very quickly because it may kickoff a job on a remote service that only after a few seconds can be assumed to be done and a followup GET would be valid.
