Since 2020/08/05 at ~16 it seems rsyslog has started failing on centrallog hosts, e.g.
```

Looks like the latest rsyslog version is significantly more stable on centrallog1001! We'll be running 8.2008.0-1~bpo10+1 on centrallog hosts only then, implementation wise these are the steps:
[x] Upgrade centrallog2001
[x] Create an APT component for rsyslog
[] Use the component on centrallog hosts only (`os_version <= buster`) and make sure the component's APT priorities are correct, so that on reimage the component's version is installed
[x] Upload rsyslog 8.2008.0-1~bpo10+1 and librelp 1.7.0-1~bpo10+1 to said component
