queue consumer setting max_batch_timeout, batch-timeout should accept 0

[w-kuhn]

What this PR solves / how to test

Fixes MQ-635

The setting for a queue consumer's batch-timeout should accept 0 as a valid value. This PR fixes a bug where 0 was being treated as falsy and sending the backend request with the value omitted.

For example:
queues consumer add testQueue testScript --env myEnv --batch-size 20 --batch-timeout 0
