[15.0][IMP] queue_job: Configure default subchannel capacity.

[amh-mw]

This adds a new subcapacity option to channels that allows the
configuration of the default capacity for autocreated child channels.

For example, environment ODOO_QUEUE_JOB_CHANNELS=root:8:subcapacity=1
would set the capacity of an autocreated root.sub channel to 1.

Hi @guewen,
some modules you are maintaining are being modified, check this out!

My own use case is that I run multi-company odoo with an environment like ODOO_QUEUE_JOB_CHANNELS=root:8,single:1. The single channel is for problem children that tend to generate an excess of SerializationFailure if executed in parallel. I've recently determined that those SerializationFailure are company-specific, so a channel per company would improve parallelism.

Per @sbidoul in OCA Discord

Undeclared channels are auto created at runtime, but with an unlimited capacity.

This setting allows me to limit the capacity of auto-created channels.

Thanks for addressing this @amh-mw

I would have a preference for configuring this in the parent channel, instead of globally.
Like this is done, for instance for the throttle config.

Understood. I will unfortunately not have time to circle back around to that request until next year. Would it be possible to mark this issuenostale?

@amh-mw Count on me to repoen it if the stale bot closes it. Can you set it Draft? [done]
