A container does not inherit its host's /etc/hosts, so a name the mesh wrote
there resolves for the machine and not for anything it runs. It fails as "could
not translate host name", which reads like a mesh that never wrote the name —
so the address is resolved on the machine and the container is given that.
And `grep -c` prints 0 and exits non-zero when it finds nothing, so the obvious
`|| echo 0` prints a second one and the count is never what it looks like. The
question was always whether, not how many.
The rotation check now also reports what psql said, not only what the
provisioner said: the failure was on the client side and the diagnostics were
all from the server.
