flow: Include flow details with higher priority log messages

Currently flow_log() and related functions / macros have a 'details'
parameter which indicates whether to add extra messages with details of the
flow's addresses.  This is still a bit awkward to invoke, and only used in
a few places.  Change the logic, to automatically include the details if
and only if the log priority is greater than LOG_DEBUG.

Rationale:

If at debug log level, there are already a bunch of debug messages tracking
the flow life cycle, which include those details (we make sure to retain
those).  It's usually pretty easy to cross reference a specific flow debug
message with the flow's history including the details.

If at higher log level, and we generate a flow-connected error or warning
we don't have those life cycle messages.  So, just giving the flow index
doesn't really tell you anything about which flow tripped the error.
Adding the address details make the error message significantly more
useful.
