op-chain-ops: log when setting storage

Adds a global logger to the `SetStorage` operation. Not ideal
that a global logger is used, but that is currently how the logging
is handled for the migration. This will help to prevent errors in
misconfiguration of the system. In setups like hive, it is difficult
to get insight into the state of the system as it is being brought
up, so this should log when the system is being brought up. Bad
config should stick out, ie setting an empty value because something
was left out of the config.
