* WIP: github issue template

* Update issue_template.md

* Create 3037_parrot_disco_mod

Add support for the Parrot Disco airframe. Tested with both Pixhawk Mini and Pixracer, using a generic 30A ESC and a Cobra 2221/16 motor.

* Update 3037_parrot_disco_mod

fixed indentation per @Dagar

* Use new generic FW wing mixer (fw_generic_wing.main.mix)

Due to flash overflow

board_shutdown should not return, but just in case

Otherwise the publication from IRQ context won't work

If needed it could be used in scripts as well.

To make sure slow param writes will finish before we hit the timeout. I've
seen param write durations of around 2s.

Prevents the system from shutting down.

px4_shutdown_request() was called from the power button IRQ callback, which
invoked a work queue callback. But on NuttX, the work queue uses a
semaphore, and thus it cannot be called from IRQ context.
This patch switches to publishing an uORB msg instead, which is handled in
the commander main thread.

To increase failure resistance, we could subscribe to the same topic in
another module for redundancy, in case commander runs wild.

This makes it easy to flip any airframe config over to HIL.

FMUv5: Ensure there is enough UART buffer space - since the board has plenty of RAM, all UARTs are treated equally
