LoadConfigFromPersistence logged a single glog.V(1) "Using default X
configuration" for every way of not loading anything, so the bug in
issue #10874 - a store handed in that the type assertion rejects, leaving
a task running on compiled-in defaults - looked exactly like the normal
"no data directory configured" case. The reporter had to read the source
to work out why their disabled task kept running, and asked for this
specifically.
Separate the cases. A non-nil store that does not provide the accessor is
always a wiring bug and is now logged at warning level, naming the type
and the missing method. A read error or a policy that will not apply is
also a warning. No persistence configured, and a store with nothing saved
yet, stay at V(1): those are normal.
