target_ops::to_stratum -> target_ops::stratum() virtual method

Given that a target's stratum is a property of the type, and not of an
instance of the type, get rid of to_stratum data field and replace it
with a virtual method.

I.e., when we have e.g., 10 target remote instances active, there's no
need for each of the instances to have their own to_stratum copy.
