Support New Netdata Swap Chart Name

[Deleh]

The swap chart was renamed from system.swap to mem.swap. Both tables are queried now in the same manner as the CPU core temperatures are, ref

Still some issues with NetData Diagnostic. Detected on mrl-7.

would it make sense to also add a new KeyValue to the diagnostics which gives us the netdata version installed on the system?
most netdata diagnostic issues where related to a new/different netdata version...

Yes, good idea 👍

This happens only on mrl-7 which has indeed a different (and newer) netdata version than mrl-8. I'll have a look how to fix this, those cpu.cpu* tables seem to have gone completely.

This seems to be an issue with netdata itself which can't gather the relevant data. The relevant CPU data isn't even shown in the web interface.

How it is

How it should be

Let's try a reboot first.

I've added the netdata version as key-value pair to CPU Info for now.

Are the changes backwards compatible with old netdata versions? If not we should not forget to update netdata on all robots (basf, afi)

The swap changes are backwards-compatible. The version was not included until now but is available on e.g. mrl-2.

@Deleh while you are on it
could you have a look at the old PR #330
if it contains something useful maybe integrate it into #338
if not, please close #330

#330 was a workaround for the mrk statemachine when we had serious problems with netdata. Malformed data should be treated as error, not as warning. I'll close it but keep the branch if we run into problems again.

Tested also on mrl-8:

Looks god

Looks good!
