Added shutdown_hook_priority to rabbitmq_server

[stijnjanmaat]

Description of the Change

When you have multiple actions taking place on the wp hook shutdown, you want to be able to postpone the shutdown of the Connection to RabbtiMQ. That's why I expanded the $rabbitmq_server config with shutdown_hook_priority.

Alternate Designs

Thought about setting the hook hard coded to PHP_INT_MAX but making it configurable is more flexible.

Benefits

You have more finegrained control of when the Connection is destroyed.

Possible Drawbacks

Maybe a bit more complex, but default behavior is unchanged.

Verification Process

I implemented fork in my project and it worked.

Hi @jeffpaul, did you get a chance to look at this request?

@stijnjanmaat not as of yet, no, but with WP 5.4 coming next week we're working in parallel to test compatibility there so expect some closer review of this PR in the near future. I appreciate your patience, thanks!
