Fixed topic parsing and filter handling

[chrfranz]

The topic parsing and filter handling was not correct according to the OEC development specification 1.0.0.

• Removed oi4Id, licenseId and topicTag from the ValidatedPayload type. All this information can now be found in the ValidatePayload.filter variable.
• MqttMessageProcessor.extractCommonInfo() now reads the subResource (if available)
• MqttMessageProcessor.extractResourceSpecificInfo() now reads the filter information that is different for each resource type.
• Updated Oi4Application.validateFilter() to be conform with the OEC development specification 1.0.0. There is no DataSetWriterId filter anymore.
• Oi4Application.sendPayload now sets the correct subResource and filter (if available).
• Updated unit tests
