missing, and misleadingly logging that they were created multiple times as
well.

the error message for failure to sync the whole namespace was too long, so
split it into two lines and make it a warning.
the namespace creation one lacked context (that the error was caused by the
remote side or the connection) and had too much (the datastore, which is
already logged very often) at the same time.

`try_exists` will return Ok(false) if the path is or containts a dangling
symlink, treat that as hard error just like if `try_exists` has returned an
Err(..).

one million chunks are a bit much, considering that chunks are representing
1-2MB (dynamic) to 4MB (fixed) of input data, that would mean 1-4TB of re-used
input data in a single snapshot.
64k chunks are still representing 64-256GB of input data, which should be
plenty (and for such big snapshots with lots of re-used chunks, growing the
allocation of the HashSet should not be the bottleneck), and is also the
default capacity used for pulling.

instead of calling this three times, call it once:
retrieving the highest backup timestamp doesn't need its own request, it can
re-use the "main" result, the corresponding helper can thus be dropped.
remove_vanished can re-use the earlier result - if anybody prunes the backup
group or adds new snapshots while the sync is running, the whole group sync is
racy and might cause spurious errors anyway.
since re-syncing the last already existing snapshot is not possible at the
moment, the code can also be simplified by treating such a snapshots already
fully synced.

a vanished namespace is one that
- exists on the target side, below the target prefix
- but within the specified max_depth
- and was not part of the synced namespaces

Adds the functionality required to push datastore contents from a
source to a remote target.
This includes syncing of the namespaces, backup groups and snapshots
based on the provided filters as well as removing vanished contents
from the target when requested.
While trying to mimic the pull direction of sync jobs, the
implementation is different as access to the remote must be performed
via the REST API, not needed for the pull job which can access the
local datastore via the filesystem directly.
