[doc] What happens when timeout period in Container.exec() elapses?

[sed-i]

ops.model and ops.pebble don't specify what happens when timeout is elapsed.
Context: canonical/alertmanager-k8s-operator#218

operator/ops/model.py

Lines 2711 to 2712 in 1836df5

	Raises:
	ExecError: if the command exits with a non-zero exit code.

operator/ops/pebble.py

Lines 2526 to 2528 in 1836df5

	timeout: Timeout in seconds for the command execution, after which
	the process will be terminated. If not specified, the
	execution never times out.

Potentially related: container.exec also leaks http.client.RemoteDisconnected, as can be seen here: canonical/cos-lite-bundle#103

We decided against putting Raises TimeoutError in these methods, because they really need to go in all of them, so there's the note in the class docstring instead.

See discussion here.

Close now.
