[FR] Auto-Issue Orders

[SchrodingersGat]

With the addition of start_date field to orders - #8966 - we now have the opportunity to automatically issue a pending order on a particular date.

That could be done via a plugin, or implemented directly into code with a simple global setting.

While I don't want to "bloat" the core code, this seems like a low hanging fruit which would be a great addition. The "extra actions on order issuing" can be handled by plugins.

So basically, add settings like AUTO_ISSUE_BUILD_ORDERS - if set, build orders will be automatically issued once the "start_date" is reached (if set)

@matmair @wolflu05 thoughts? If you agree I'll add this in once #8966 is closed

@SchrodingersGat this seems like a great candidate for a built in plugin; keeping the core logic lean should be a focus to make faster release cycles possible
