remove proxmox-rrd-api-types crate, s/RRDTimeFrameResolution/RRDTimeFrame/
...
Because the types used inside the RRD have other requirements
than the API types:
- other serialization format
- the API may not support all RRD features

proxmox-rrd: use a journal to reduce amount of bytes written
...
Append pending changes in a simple text based format that allows for
lockless appends as long as we stay below 4 KiB data per write.
Apply the journal every 30 minutes and on daemon startup.
Note that we do not ensure that the journal is synced, this is a
perfomance optimization we can make as the kernel defaults to
writeback in-flight data every 30s (sysctl vm/dirty_expire_centisecs)
anyway, so we lose at max half a minute of data on a crash, here one
should have in mind that we normally expose 1 minute as finest
granularity anyway, so not really much lost.
