only warn about missing/invalid Date field for now
The Date field in the Release file is useful to avoid allowing an attacker to 'downgrade' a user to earlier Release files (and hence to older states of the archieve with open security bugs). It is also needed to allow a user to define min/max values for the validation of a Release file (with or without the Release file providing a Valid-Until field). APT wasn't formally requiring this field before through and (agrueable not binding and still incomplete) online documentation declares it optional (until now), so we downgrade the error to a warning for now to give repository creators a bit more time to adapt – the bigger ones should have a Date field for years already, so the effected group should be small in any case. It should be noted that earlier apt versions had this as an error already, but only showed it if a Valid-Until field was present (or the user tried to used the configuration items for min/max valid-until). Closes: 809329
