previously the BackGroup trait used the datastore's
namespace_path() method to construct a base path. this would result in
it returning an absolute path equivalent to full_group_path(). use
the namspace's path() method instead to get a relative path, in-line
with backup_dir's relative_path().

the remaining ones are:
- type complexity
- fns with many arguments
- new() without default()
- false positives for redundant closures (where closure returns a static
value)
- expected vs actual length check without match/cmp

In the API we want to iterate over all backup groups
belonging to a particular type at least once, and iterating
through *everything* and simply "skipping" over every single
entry from another type makes no sense given that the groups
are organized into subdirectories based on their type.
Let's have an `.iter_backup_type()` method which returns an
iterator over all the groups of a specific type named
ListGroupsType and factorize the type level iterator out of
ListGroups for reuse.

We got the digest available anyway, and it's only 16 bytes more to
save (compared to last_generation and the recently removed last_time,
both being 64 bit = 8 bytes each)
Side benefit, we detect config changes made manually (e.g., `vim
datacenter.cfg`) immediately.
Note that we could restructure the maintenance mode checking to only
be done after checking if there's a cached datastore, in which case
using the generation could make sense to decide if we need to re-load
it again before blindly loading the config anyway. As that's not only
some (not exactly hard but not really trivial like a typo fix either)
restructuring work but also means we'd lose the "detect manual
changes" again I'd rather keep using the digest.

When re-opening a datastore due to the cached entry being stale
(config change) but also if the last re-open was >60s ago). On
datastore open the chunk store was also re-opened, which in turn
creates a new ProcessLocker, loosing any existing shared lock which
can cause conflicts between long running (24h+) backups and GC.
To fix this, reuse the existing ChunkStore, and thus its
ProcessLocker, when creating a up-to-date datastore instance on
lookup, since only the datastore config should be reloaded. This is
fine as the ChunkStore path is not updatable over our API.
This was always a potential issue but got exposed in practice by
commit 118deb4db8e709b02704bc66c0551bfa7e4369ed which introduced the
unconditional "re-open after 60s" mechanism.

We probably want to use a separate property to safe this to avoid
confusion with size.

When listing the content of a catalog, add the number of files
contained in the directory as its size. Also removes redundant code,
the `mtime` and the `size` of a file is already set when creating the
archive entry, but we naturally need to override the size now for
directories.

other sizes can happen in legitimate and illegitimate ways:
- illegitimate: encryped chunks and bad actor client
- legitimate: same chunk but newer zstd version (or compression
level) can compress it better (or worse) so the
Ideally we could take the actual smaller chunk so that improved zstd
tech gets leveraged, but we could only allow to do that for
un-encrypted ones.

We sometimes need to do some in-memory only stuff, e.g., to check if
GC is already running for a datastore, which is a try_lock on a mutex
that is in-memory.
Actually the whole thing would be nicer if we could guarantee to hold
the correct contract statically, e.g., like
