This is a more convenient way to pass along the key when
creating encrypted backups of unprivileged containers in PVE
where the unprivileged user namespace cannot access
`/etc/pve/priv`.

Have a single common function to get the BaseDirectories
instance and a wrapper for `find()` and `place()` which
wrap the error with some context.

place() is used when creating a file, as it will create
intermediate directories, only use it when actually placing
a new file.

This also replaces the recently introduced --encryption
parameter on the client with a --crypt-mode parameter.
This can be "none", "encrypt" or "sign-only".
Note that this introduces various changes in the API types
which previously did not take the above distinction into
account properly:
Both `BackupContent` and the manifest's `FileInfo`:
lose `encryption: Option<bool>`
gain `crypt_mode: Option<CryptMode>`
Within the backup manifest itself, the "crypt-mode" property
will always be set.

This can be used to explicitly disable encryption even if a
default key file exists in ~/.config.

And use it for fixed and dynamic index. Please note that this
changes checksums for fixed indexes, so restore older backups
will fails now (not backward compatible).
To support incremental backups (where not all chunks are sent to the
server), a new parameter "reuse-csum" is introduced on the
"create_fixed_index" API call. When set and equal to last backups'
checksum, the backup writer clones the data from the last index of this
archive file, and only updates chunks it actually receives.
In incremental mode some checks usually done on closing an index cannot
be made, since they would be inaccurate.

if *only* data chunks are registered (high chance during incremental
backup), then chunk_count might be one lower then upload_stat.count
because of the zero chunk being unconditionally uploaded but not used.
Thus when subtracting the two, an overflow would occur.
In general, don't let the client make the server panic, instead just set
duplicates to 0.

error on mounting and have a zpool that is not imported
and disks that are used
