In Python 3.5 json.tool was changed to produce unsorted output and
--sort-keys option was added to compensate. This wasn't caught by
4fe245cc2f ("qa: update krbd tests for python3") because it raced
with 50933b863a ("qa: krbd_exclusive_option.sh: update for recent
kernel changes").

Since 5.3:
- a plain "rbd map" acquires the lock, so it's not different from
"rbd map -o exclusive" in this regard
- if the lock is held by the exclusive peer, I/O is failed right away
instead of blocking
- lock_timeout option is respected only by "rbd map" and not by I/O
Since 5.5:
- if the mapping is read-only, the lock isn't acquired
Added blacklisting test case, dropped lock_timeout test case.

Avoid sporadic failures in combination with msgr-failures/many.yaml,
where assert_locked() might take over 10 seconds.

/bin/bash is a Linuxism. Other operating systems install bash to
different paths. Use /usr/bin/env in shebangs to find bash.
