In previous PR #1735 , the sequential order has been added into CommSpec, which integrate into a CommAction object. In this PR, all the handlers using CommSpec wiil be updated to use CommAction.

Summary of code changes

1. Add comm_type to CommAction object, and if the CommType is BEFORE, an identifier such as arg_index or key_for_kwarg will be added.
2. We distinguish the parameters and non-parameters tensor. For Parameters grad, a hook function will be registered to param, however, a runtime communication node will be added for a non-parameter tensor.
