LU-13805 osd: Implement unaligned DIO connect flag

LU-13805 osd: Implement unaligned DIO connect flag

Unupgraded ZFS servers may crash if they received unaligned
DIO, so we need a compat flag and a test to recognize those
servers.

This patch extracts server-side logic from two master patches
to improve interop testing, but does not implement client UDIO.
