Fire and forget HTTP requests

[heloineto]

Is your feature request related to a problem? Please describe.
Currently, the bot has to wait for an HTTP request to be completed, even if it does not use the response. This slows down the bot and results in worse UX.

Describe the solution you'd like
A "fire and forget" option on the HTTP request block, so that the bot can proceed with the conversation without waiting

Describe alternatives you've considered
Using a Script block with fetch
