Description of the Change

If a provider wants to provide a way for the ESR to check the status of the environment they provide then they can now set the 'status_request' key to a dictionary of the 'request' style. Similar to how the executor describes a request.

{
    "method": "GET",
    "url": "http://url.com"
}

Any extra parameter allowed by the requests library is possible.

Is there risk of a race condition during termination, when self.finished is still False, but self._environment_active() already returns False?

Should this be written to the OpenTelemetry span?

Will it be robust enough if one failed check leads to termination? Even if there are retries.

Should an error like this return None, to indicate that health check was inconclusive? So that a few more retries could be done?

In other words, False should be returned only when we know for sure that the environment is inactive.
