enhance: allow users to disable broker heartbeats

[smart-programmer]

broker heartbeats clutter the logs console which prevents users from seeing important logs. this allows users to disable broker heartbeats if timeout isn't provided.

reference issue

the change seems feasible, however, is it possible for you to add some additional tests for the change?

Hello,

I took the liberty to add a test case for this change. However I'm failing to add to a pull request as I'm new to git and I get a permission denied pushing to smart-programmer branch. No clue how to do it. I however attached a patch file to add the change in t/unit/test_mixins.py. Would that test case be enough for the proposed change? (I somehow cannot upload .patch so used .txt instead)

thanks for the test! you have to open a PR on smart-programmer:enhance/disable-heartbeat-no-timeout branch. if you can't do that we will add the test from your provided code!
