82f5ad18f0 proxmox-rrd: move unshipped cli tool to examples 
it's a rather low-level tool mostly useful for debugging and some of
it is rather "dumb" (by design) anyway, e.g., it does not
transparently applies journal but really only operates on the DB
files as is (which can conflict with daemon operations).

In summary, not (yet) a tool meant for end user consumption.
Move it to examples folder to avoid compilation on packaging (we do
not ship it anyway) which allows us to move the rather expensive
proxmox-router (pulls in hyper) to the dev-dependencies section.

c68fa58a59 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

1d44f175c6 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.
