Add custom output name setting (useful for shim)

[lirannl]

Let me know if you'd like me to change the description of the setting

[Maryse47]

I'm curious why do you need shim with self-enrolled keys? Or you didn't self-enroll keys?

Note that a global OUTPUT_NAME setting would break with multiple kernels/configurations.

35a33ffdc5edafbdc46ec581e54ddadb42b42b23 implements a per-configuration solution.
