And drop the base_path parameter on a first bunch of
functions (more reordering will follow).

db87d93efc make datastore BackupGroup/Dir ctors private
And use the api-types for their contents.

These are supposed to be instances for a datastore, the pure
specifications are the ones in pbs_api_types which should be
preferred in crates like clients which do not need to deal
with the datastore directly.

988d575dbb api-types: introduce BackupType enum and Group/Dir api types
The type is a real enum.

All are API types and implement Display and FromStr. The
ordering is the same as it is in pbs-datastore.

Also, they are now flattened into a few structs instead of
being copied manually.

de015ce7e1 datastore: implement Iterator for backup group listing
While currently it's still only used in a collected() way, most call
sites can be switched over to use the iterator directly, as often
they already convert the not-so-cheap, in-memory vector back in
.into_iter() anyway.

somewhat also preparatory (yak shaving) work for namespaces

c90dbb5c7b datastore: move list_backup_groups into Datastore impl
Having that as static method in BackupInfo makes zero sense and just
complicates call sites, which need to extract the base_path from the
store manually upfront.

Mark old fn as deprecated so that we can do the move in a separate
step.

It's also planned to add an Iterator impl for this to allow more
efficient usage in the future.

4bc84a6549 pbs-datastore: add active operations tracking
Saves the currently active read/write operation counts in a file. The
file is updated whenever a reference returned by lookup_datastore is
dropped and whenever a reference is returned by lookup_datastore. The
files are locked before every access, there is one file per datastore.

118deb4db8 pbs-datastore: use ConfigVersionCache for datastore
instead of relying on the content of some configs

previously, we always read and parsed the config file, and only
generated a new config object when the path or the 'verify-new' option
changed.

now, we increase the datastore generation on config save, and if that
changed (or the last load is 1 minute in the past), we always
generate a new object

fef61684b4 datastore: add tuning option for chunk order
currently, we sort chunks by inode when verifying or backing up to tape.
we get the inode# by stat'ing each chunk, which may be more expensive
than the gains of reading the chunks in order

Since that is highly dependent on the underlying storage of the datastore,
introduce a tuning option  so that the admin can tune that behaviour
for each datastore.

The default stays the same (sorting by inode)
