this change reverts 17d2bc3707, before
we recreate a chacra repo hosting libpmem packages, we are not able
to query the repo from shaman or pull the dependencies from chacra.
in future, we should be able to get the libpmem dependencies from
offical ubuntu package repo and fedora, CentOS Stream and RHEL repos.

Establishing a watch on rbd_mirroring object and skipping rescanning
image mirror snapshots on periodic refresh unless rbd_mirroring object
gets notified in the interim is flawed. rbd_mirroring object is
notified when mirroring is enabled or disabled on some image (including
when the image is removed), but it is not notified when images are
promoted or demoted. However, load_pool_images() discards images that
are not primary at the time of the scan. If the image is promoted
later, no snapshots are created even if the schedule is in place. This
happens regardless of whether the schedule is added before or after the
promotion.
This effectively reverts commit 69259c8d37 ("mgr/rbd_support: make
mirror_snapshot_schedule rescan only updated pools"). An alternative
fix could be to stop discarding non-primary images (i.e. drop
if not info['primary']:
continue
check added in commit d39eb283c5 ("mgr/rbd_support: mirror snapshot
schedule should skip non-primary images")), but that would clutter the
queue and therefore "rbd mirror snapshot schedule status" output with
bogus entries. Performing a rescan roughly every 60 seconds should be
manageable: currently it amounts to a single mirror_image_status_list
request, followed by mirror_image_get, get_snapcontext and snapshot_get
requests for each snapshot-based mirroring enabled image and concluded
by a single dir_list request. Among these, per-image get_snapcontext
and snapshot_get requests are necessary for determining primaryness.

There is a difference: non-primary means NON_PRIMARY promotion state,
while "not primary" can refer to any of NON_PRIMARY, ORPHAN or UNKNOWN
promotion states.

It was botched in commit 2bca9ee96c ("rbd-mirror: consolidate
prepare local/remote image steps to bootstrap") and went unnoticed
because currently no special handling is needed for disconnected
clients -- is_disconnected() check happens to be the last step
and it doesn't generate an error.

Replay and resync should generally be skipped if the remote image is
not primary.
If this is not done for replay, snapshot-based mirroring can run into
a livelock if the primary image is demoted while a mirror snapshot is
being synced. On the demote site, rbd-mirror would pick up the just
demoted image, grab the exclusive lock on it and idle waiting for a new
mirror snapshot to be created. On the (still) non-primary site,
rbd-mirror would eventually finish syncing that mirror snapshot and
attempt to unlink from it on the demote site. These attempts would
fail with EROFS due to exclusive lock being held in the "refuse proxied
maintenance operations" mode, blocking forward progress (syncing of the
demotion snapshot so that the non-primary image can be orderly promoted
to primary, etc).
If this is not done for resync, data loss can ensue as the just demoted
image would be immediately trashed, underneath the non-primary site that
is still syncing.
Currently this is done in PrepareReplayRequest only for journal-based
mirroring. Note that it is conditional: if the local image is linked
to the remote image, proceeding is desirable.
Generalize this check, consolidate it with a related check in
PrepareRemoteImageRequest and move the result to BootstrapRequest to
cover both "local image does not exist" and "local image is unlinked"
cases for both modes.

Initialize local_promotion_state and remote_promotion_state to UNKNOWN
instead of counterintuitive PRIMARY and NON_PRIMARY -- half the time the
final values are flipped. Then is_local_primary() and is_linked() can
be strengthened as a non-existent image should stay in UNKNOWN.
