[docs] [issue30935] document the new behavior of get_event_loop() Python 3.6

[Chris Jerdonek]

New submission from Chris Jerdonek:

Currently, the Python asyncio.get_event_loop() docs don't say that get_event_loop() returns the currently running event loop when it is called from a coroutine:

https://docs.python.org/3/library/asyncio-eventloops.html#asyncio.get_event_loop
https://docs.python.org/3/library/asyncio-eventloops.html#asyncio.AbstractEventLoopPolicy.get_event_loop

This is new behavior that was introduced in Python 3.6 in this issue:
https://github.com/python/asyncio/pull/452

Without this, the docs make it seem like get_event_loop() should return the loop that was last passed to set_event_loop().

This could be added with a "Changed in version 3.6" note.
