Task hash should probably also include the init args of a TaskClass()

[jhnwu3]

We need to probably for reproducibility reasons:

• include task init args here as part of either the task_name or the hash string such that small changes to the task init will re-cache and be uniquely documented so people can adequately log small changes here.
• also, add some type of documentation + print statement here to notify users that their task cache is stored based on these parameters.
