[uamqp] Remove loop as a param

[YijunXieMS]

Python 3.10 asyncio will remove loop as a param in some functions. For instance, asyncio.sleep(), shield(), wait_for(), etc. Uamqp should remove them.
Python 3.8 asyncio has deprecated param loop in these functions.

quick notes:

• if loop is positional, raise TypeError for 3.10
• we should find all the SB/EH public leaking places
  • positional argument
  • keyword argument
    • we have more flexibility if it's kwargs we could do docstring/logging stuff
