feat: expiration by seconds

[aditbisa]

The only use case that I can think for this feature (other than for my interview code challenge) is:

• REST API app:
  • That means stateless.
  • Auth using bearer token only.
• And backend need to provide a broadcast endpoint for Websocket / EventSource (SSE):
  • Web API for Websocket / EventSource (SSE) cannot send custom headers.
  • As it is stateless, cookies & session is out of options.
  • The only option is token send as URL query.
• And token for Websocket / EventSource (SSE):
  • One time only.
  • Short lived (< 10 seconds)

Thanks for your pull request to Laravel!

Unfortunately, I'm going to delay merging this code for now. To preserve our ability to adequately maintain the framework, we need to be very careful regarding the amount of code we include.

If you feel absolutely certain that this code corrects a bug in the framework, please "@" mention me in a follow-up comment with further explanation so that GitHub will send me a notification of your response.
