As serde_json will otherwise read files 1 byte at a time.
Writing is a bit better, but syntacitcal elements (quotes, braces,
commas) still often show up as single write syscalls, so use BufWriter
there as well.
Note that while we do store the file in the resulting objects, we do not
need to keep the buffered read/writers as we always `seek` to the
beginning on further file operations.

Avoids latency for restore-VMs that are finished fast but not ready
yet the first round while not checking to often for slower ones, iow,
we assume that the start up distribution is looking like a chi-square
Χ² with k=3.
With 25*round we get at max 45 rounds totalling to 25.875 s delay and
1.125 max between-round delay, which still provides an ok reaction
time.

the timeout for connecting may be much shorter if we get a response
(which doesn't needs to be Ok, e.g., "Connection refused"), so
instead of trying a fixed amount of 60 times lets try for 25s
independent of how often that will be then.

- imported pbs-api-types/src/common_regex.rs from old proxmox crate
- use hex crate to generate/parse hex digest
- remove all reference to proxmox crate (use proxmox-sys and
proxmox-serde instead)

Also moved pbs-datastore/src/crypt_config.rs to pbs-tools/src/crypt_config.rs.
We do not want to depend on pbs-api-types there, so I use [u8;32] instead of
Fingerprint.
This also moves a couple of required utilities such as
logrotate and some file descriptor methods to pbs-tools.
Note that the logrotate usage and run-dir handling should be
improved to work as a regular user as this *should* (IMHO)
be a regular unprivileged command (including running
qemu given the kvm privileges...)
