[Feature] Optimize the Docker architecture

[timerring]

Is your feature request related to a problem? Please describe.

In current version, the docker is comprised of the record module(which I use the blrec lib) and postprocess module, but this is not the best practice of docker.

In fact, the Docker container should be stateless. This means it's easy to check if the service is still operational. Also, files generated by the services shouldn't be stored within the Docker container itself. This is to avoid potential file loss in case the service goes down or other unforeseen circumstances occur.

Describe the solution you'd like

In the next version, we should separate the recording and processing modules into different Docker containers, and have both of them mount the same volume. This way, we can retain the files even if the service goes down. Additionally, we can make full use of webhooks and attempt to use Kubernetes for composition to manage the services more effectively.
