Specifying the transfer-last parameter limits the amount of backups
that get synced via the pull command/sync job. The parameter specifies
how many of the N latest backups should get pulled/synced. All other
backups will get skipped.
This is particularly useful in situations where the sync target has
less disk space than the source. Syncing all backups from the source
is not possible if there is not enough disk space on the target.
Additionally this can be used for limiting the amount of data
transferred, reducing load on the network.
The newest backup will always get re-synced, regardless of the setting
of the transfer-last parameter.

a non capturing group is '(?:)' not '(:?)' so fix that.
None of these regexes are used where would use capturing groups.
DATASTORE_MAP_REGEX and TAPE_RESTORE_SNAPSHOT_REGEX are only used
as api types and BLOCKDEVICE_NAME_REGEX is only used once outside of the
api and there we also don't look at the capturing groups.

rationale is that it makes the backup much safer than 'none', but does not
incur a big of a performance hit as 'file'.
here some benchmark:
data to be backed up:
~14GiB semi-random test images between 12kiB and 4GiB
that results in ~11GiB chunks (more than ram available on the target)
PBS setup:
virtualized (on an idle machine), PBS itself was also idle
8 cores (kvm64 on Intel 12700k) and 8 GiB memory
all virtual disks are on LVM with discard and iothread on
the HDD is a 4TB Seagate ST4000DM000 drive, and the NVME is a 2TB
Crucial CT2000P5PSSD8
i tested each disk with ext4/xfs/zfs (default created with the gui)
with 5 runs each, inbetween the caches are flushed and the filesystem synced
i removed the biggest and smallest result and from the remaining 3
results built the average (percentage is relative to the 'none' result)
result:
test none filesystem file
hdd - ext4 125.67s 140.39s (+11.71%) 358.10s (+184.95%)
hdd - xfs 92.18s 102.64s (+11.35%) 351.58s (+281.41%)
hdd - zfs 94.82s 104.00s (+9.68%) 309.13s (+226.02%)
nvme - ext4 60.44s 60.26s (-0.30%) 60.47s (+0.05%)
nvme - xfs 60.11s 60.47s (+0.60%) 60.49s (+0.63%)
nvme - zfs 60.83s 60.85s (+0.03%) 60.80s (-0.05%)
So all in all, it does not seem to make a difference for nvme drives,
for hdds 'filesystem' increases backup time by ~10%, while
for 'file' it largely depends on the filesystem, but always
in the range of factor ~3 - ~4
Note that this does not take into account parallel actions, such as gc,
verify or other backups.

currently, we don't (f)sync on chunk insertion (or at any point after
that), which can lead to broken chunks in case of e.g. an unexpected
powerloss. To fix that, offer a tuning option for datastores that
controls the level of syncs it does:
* None (default): same as current state, no (f)syncs done at any point
* Filesystem: at the end of a backup, the datastore issues
a syncfs(2) to the filesystem of the datastore
* File: issues an fsync on each chunk as they get inserted
(using our 'replace_file' helper) and a fsync on the directory handle
a small benchmark showed the following (times in mm:ss):
setup: virtual pbs, 4 cores, 8GiB memory, ext4 on spinner
size none filesystem file
2GiB (fits in ram) 00:13 0:41 01:00
33GiB 05:21 05:31 13:45
so if the backup fits in memory, there is a large difference between all
of the modes (expected), but as soon as it exceeds the memory size,
the difference between not syncing and syncing the fs at the end becomes
much smaller.
i also tested on an nvme, but there the syncs basically made no difference

We can have those in existing verify jobs configs, and that'd break
stuff. So, even while the "bad" commit got released only recently
with `2.1.6-1` (14 April 2022), we still need to cope with those that
used it, and using some serde parser magic to transform on read only
is hard here due to section config (json-value and verify currently
happen before we can do anything about it)
