Enable logging for sub asset classes

Summary:
Thrift is a special integration in which it can be the parent asset class of other asset classes.  There are instances in which we want to get the logging for the sub classes without creating a standalone PolicyEnforcer class for that sub class.

## This diff
Enable thrift policy enforcer to decide which asset class gets returned for logging. Right now we want logging for Cachius, other asset classes will keep defaulting to Thrift
