Centralize dynamic config

[Sushisource]

We have some hardcoded dynamic config values for embedded server here: https://github.com/temporalio/features/blob/main/cmd/run.go#L208

As well as a file for the docker way of running things here:
https://github.com/temporalio/features/blob/main/dockerfiles/dynamicconfig/docker.yaml

We should use one file, I suppose keep the yaml format, so that we always use the same options.

Another motivation for this is that the server folks would like to use it so they know what options should apply to server when they're running it in a full infra environment for nightly pipelines.
