Make containerId optional in the event json file

During the PDR exchange, normalization causes the container IDs of
remote entities to change. Therefore, checking for a predefined
container ID from a remote terminus for sensor events does not provide
any benefit. This commit adds support for optionally skipping the check
for remote container id for sensor events when needed.

Tested:
Unit tests passed.
