Fix misspelled keyword argument poll_interval for method acquire

[XuehaiPan]

Fix misspelled keyword argument poll_interval for method acquire. Fixes #62.

I tried my best to add the backward compatibility layer in this PR to not break existing codebases.

Can you please add a test to validate this?

I think we can reimplement this by using decorators without changing the signature of the method.

I think the current implementation is fine, no need for decorators.

Thanks for your contribution.

@ofek Can you try to run python -W error xxx.py or pytest ... -W error to see what module uses the old argument poll_intervall?

Thanks, found it!
