Creates a container status to be used as a precondition

Valid values for the status parameters are:
- a string, such as 'detached', 'added', 'started', 'running'
- an object, such as { added: true, started: true, running: false }

@param {object} original - the container
@param {object|string} status - the status to set.
@param {object} parent - the parent container's id.
