Motivation for this function is the fact that some models -
e.g., very complex machine learning models fit to large datasets -
may take a long time to complete. Splitting the model creation
request from model retrieval in these cases allows the user to
perform other interactive R session tasks between the time the
model creation/update request is made and the time the final
model is available.
GetModelFromJobId also can be used to retrieve some information about
frozen model, however then some frozen specific information (parentModelId)
will not be returned.
