Consistently name threadlocal and contextvars helper functions

[MarkusH]

The threadlocal and contextvars integrations use a different naming for their functions to bind, unbind, merge and clear the context. This came up as part of #236 and e3a6213.

I'd like to propose the following function names:

• contextvars
  • merge_contextvars_context
  • clear_contextvars_context
  • bind_to_contextvars_context
  • unbind_from_contextvars_context
• threadlocal
  • merge_threadlocal_context
  • clear_threadlocal_context
  • bind_to_threadlocal_context
  • unbind_from_threadlocal_context -- doesn't exist but should probably be added

Hmm that seems a little bit too repetitive and wordy. 🤔

Maybe the best way forward is to just drop the context from merge and be done with it? Typing bind_to_contextvars_context() whenever you do something doesn't seem like a pragmatic API. :)

lol #239

Yeah I'm just gonna drop all the contexts unless someone wants to stop me.

Sounds good to me 👍
