Make it easier to find custom bot modules when using zulip-botserver

[timabbott]

I don't have a specific proposal, but probably some combination of documenting PYTHONPATH and adjusting how we search for bot modules is well worth doing to make it easier to help folks who are not deeply familiar with Python get bots running successfully. This thread has discussion https://chat.zulip.org/#narrow/stream/92-learning/topic/bot.20basics/near/1068769.

The first step for this issue is coming up with specific proposals for how to improve the implementation or documentation.

I saw this and wondered if at least for our packaged bots the registration implementation which I started working on in #517 may be useful?

Can I work on this

@b-thebest There is no firm plan for going about this yet, so as Tim mentioned we likely want a proposal for fixing it first - I'd suggest discussing ideas in #integrations on chat.zulip.org.

@PIG208 do you think #708 resolved this? I guess we can leave this option open until wethe documentation feels good for this workflow.
