Add function to get simulation parameters from alfalfa model

[tanushree04]

It would be useful to add a function to alfalfa-client, to read simulation parameters such as start time and end time, when the model is running. The function could pass in model ID as an argument, and return a dictionary of simulation parameters that were added to the model ID

This would help in adding simulation logic to alfalfa models (for e.g. if simulation time = start time + 1 hour, set input battery signal = 1)
