Invocations of Channel#basicPublish is blocking

Invocations of Channel#basicPublish is blocking if a resource-driven alarm is in effect.
We need to add default timeout and ability to set up this timeout in consumer.

An ideal solution would be to have a cancellable coroutine, but I am afraid the only way to interrupt this blocking call is to close the channel.

@Wrover There is withTimeout method, we can use it with default timeout and provide a way to set it up. Another option is blocking connections notification

The latter is worthwhile, I'll read it. Regarding withTimeout I am still struggling writing a working example. Take a look if you wonder -- https://gist.github.com/wrover/0becefe45bcc1d6110be96e1e6354f26
