The commands initializing a new device (mkfs, device add) do discard by
default, while this is missing from replace start. For parity add the
options with same name and semantics.

The exclusive ops will not start if there's one already running. Now
that we have the sysfs export (since kernel 5.10) to check if there's
one already running, use it to allow enqueueing of the operations as a
convenience.
Supported enqueuing:
btrfs balance start --enqueue
btrfs filesystem resize --enqueue
btrfs device add --enqueue
btrfs device delete --enqueue
btrfs replace start --enqueue
This patch implements the functionality based on Goldwyn's patch
https://lore.kernel.org/linux-btrfs/?q=20200825150338.32610-4-rgoldwyn%40suse.de
but on top of previous preparatory patches.
Note that 'filesystem resize' options could confuse getopt as the
negative size change looks like a series of short options and there's no
way to make getopt ignore the short options, so there's a custom option
parser.

This example in device replace doesn't render properly in browsers,
think it's just misuse of syntax. Unfortunately, the github preview
renderer doesn't seem to catch that. Otherwise, manual page and html
rendering is ok.
The syntax uses Example delimited block:

A few minor benefits:
* editors set highliting according to the extensions
* web access to the git repository (github) renders the .asciidoc
files:
* we can link to them from the wiki
* the files are editable via browser and such editations can be
submitted for merge easily
