Proposed change

With this update denonavr is going async. It is using httpx instead of requests now and is 100% async.

There are a few bugs which are already identified and fixed in dev version of denonavr or in progress:
- non functional play-pause toggle
- improvement of 403 error handling of AVR-X 2016 receivers

I would like to collect some fixes and add fixes for potential issues discovered here during review.
That's why I did not set the "local tests pass" flag yet. Please start reviewing the changes anyhow. There is a bunch of them.

Known bugs are fixed, ready to proceed.

The config flow tests are broken because they are using internal variables which changed. I'm fixing that, but my local tox run is taking ages.

@bdraco finally found the memory leak. It was related to an lru cache, which is cleared now on exceptions. I just did a rebase too.

btw. it could take a while until garbage collector found the instances from the cleared cache. Thus, object count might go up and down

The change to include the exception cause when raise ConfigEntryNotReady made it in so I think its now possible to remove a lot of the code.

Suggested change (should cherry-pick cleanly) bdraco@c94efca

2021-04-01 04:28:16 WARNING (MainThread) [homeassistant.config_entries] Config entry 'Marantz NR1711' for denonavr integration not ready yet: NetworkError: [Errno 113] Connect call failed ('192.168.107.153', 8080); Retrying in background

The great part here is it will automatically take care of downgrading retries to debug with a lot less code to maintain.

Handling in Config Flow needed to be adapted slightly because it cannot handle ConfigEntryNotReady.
