dnsdist: allow skipping arbitrary EDNS options when computing packet hash #10791

Short description

This adds a new option to newPacketCache() to skip arbitrary EDNS options when hashing packets.
I was a bit unsure to keep the cookieHashing setting but this makes the lua configuration more readable.

It also affects recursor's packet cache so must be reviewed carrefully.

Fix #10585


I have:

  • read the document
  • compiled this code
  • tested this code
  • included documentation (including possible behaviour changes)
  • documented the code
  • added or modified regression test(s)
  • added or modified unit test(s)
