sent a v2 with patches for qemu-server and container rebased as they did
not apply cleanly anymore.

this series does two things:
* switch the RRD API backend to use the old RRD files is available
* only data for frontend graphs
* PNG generation
* always use RRD files with the new 9.0 schema in pmxcfs/status.c
* hardcode pve-TYPE-9.0 paths in the RRD api endpoints for
* nodes
* VMs
* CTs
* Storage
The motivation for the combination of old and new RRD files is that during the
migration of old RRD files to the new ones, spikes get flattened. By combining
the old and new RRD files, we can keep the old coarse data with all it spikes
and only show the new much mode finer stepped data where available.
This also enables us to just write any new data into an RRD file that is
created with the new 9.0 schema. As a result, no migration step is needed
anymore and we can simplify the logic around the whole "does the only the old
file exist or is the new one also present" alot in quite a few places.
This series does not remove the rrd migration tool or its dependencies. That
still needs to happen. We want to keep the check in the pve8to9 tool, because we
will need the additional space in any case.
