[DRBD-user] drbd-utils-9.4.0

This release was mainly driven by some nice new features. The main
feature is that "drbdsetup status" now exposes various detailed verify
and resync statistics (if you have the latest kernel module and you turn
on the according switches in drbdsetup). In the json output you might
want to check for "has-sync-details" and "has-online-verify-details" to
decide if the detailed information is available.

IMPORTANT: If you are a user of "drbdsetup status --json", please note
that the output for "client/peer-client" was changed to proper bool
types. This is the output that informs you that the local disk/peer disk
is intentional diskless (or not). Further, the "quorum" field, while
having a bool type, was printed as string "true"/"false". I decided to
break compat (but fix) that, as there are not many users that actually
use the json output, especially these rather "new" features (intentional
diskless/quorum). Still, if you already use these fields in the json
output, please adapt your scripts!

All in all that should be a rather calm release, and if you are happy
with the latest bug fix release (v9.3.1), there is no urgent need to

 * drbdmeta: don't exit with negative return codes
 * usage counts: only register if we know driver version
 * drbdsetup,v9: expose detailed verify/resync statistics
 * drbdsetup,v9,json: saner types for client/peer-client/quorum on
 * drbdsetup,v9: expose client/peer-client in status if !isatty()
