New Feature: `synchronize()`

[`synchronize()`](https://github.com/brainix/pottery#synchronize) is a decorator that allows only one thread to execute a function at a time. Under the hood, `synchronize()` uses a Redlock, so refer to the [Redlock documentation](https://github.com/brainix/pottery#redlock) for more details.

What's Changed
* Choose a random Redis database for unit tests by brainix in https://github.com/brainix/pottery/pull/302
* Implement and test redlock() decorator by brainix in https://github.com/brainix/pottery/pull/303
* Choose Redis database 1 for doctests by brainix in https://github.com/brainix/pottery/pull/304
* Rename redlock() decorator to synchronize() by brainix in https://github.com/brainix/pottery/pull/305
* Move CI to GitHub Actions by brainix in https://github.com/brainix/pottery/pull/307
* Skip slow doctests; update status badges by brainix in https://github.com/brainix/pottery/pull/308
* Author documentation for synchronize() decorator by brainix in https://github.com/brainix/pottery/pull/306

Bug Fix: `._scan()` in `RedisCounter._make_counter()`

Previously, we were calling `._scan()` multiple times, and using only every other `._scan()` call's results, and never using `encoded_dict`.

Now, we're using `encoded_dict` and not skippinng over every other `._scan()` call.

In practice, this meant that `RedisCounter.most_common()` yielded wrong results. It's fixed in this release.

Optimization: When possible, bail out early when quorum achieved

The beating heart of all consensus based distributed algorithms is to scatter a computation across multiple nodes, then to gather their results, then to evaluate whether quorum is achieved.

In some cases, _quorum_ requires gathering all of the nodes' results (e.g., interrogating all nodes for a maximum value for a variable).

But in other cases, _quorum_ requires gathering only `n // 2 + 1` nodes' results (e.g., figuring out if > 50% of nodes believe that I'm the owner of a lock).

Implement the logic to "bail out" early when possible, in the latter case.
