[Bug 1868587] [NEW] Module 'pg_autoscaler' has failed: division by zero

[Frode Nordahl]

Public bug reported:

While enabling Ceph RadosGW on Bionic/Ussuri I have run into
intermittent failures which appear to be caused by the PG autoscaler.

HEALTH_ERR Module 'pg_autoscaler' has failed: division by zero

It has recently been fixed upstream [0][1] and I do not think we have
this in our packages.
