TST: add end-to-end tests with RE/db

[mrakitin]

A follow-up PR to #6 to complement the test suite with the integration tests using RunEngine and databroker instances.

I've also noticed some linter issues/suggestions when running it locally (the pylint checks are currently disabled in the CI config):

I would rather not weigh down this lightweight and general-purpose package with tests for a specific use case that has a lot of dependencies. Perhaps a more targeted test can do what we need here: for example, a test that the built-in json module can serialize a deep copy of a nested RedisJSONDict. If that works, then Bluesky, Databroker, Kafka, and other applications will be happy.

[mrakitin]

It's fair. On the other hand, those tests can (1) uncover unforeseen integration/dependencies issues with the bluesky stack, and (2) demonstrate how to hook it to another software, in this case, bluesky. We don't inject any bluesky dependencies into the requirements, only optional.

We have to have those tests somewhere - probably profile-collection-ci is a better place for that.

Closing. I has to live elsewhere.
