Description of work

• Add Maven protobuf/grpc plugin for compiling protobuf files
• Add protobuf files with messages describing data points, point values and events
• Add gRPC server to Mango Core with configurable TLS/mTLS support
• Other modules/core may in the future use the same gRPC port to expose more services
• gRPC is configured to use TLS encryption via mango.properties file, the server may also authenticate the clients via mTLS
• Add way to register a universal event "handler" (really a listener interface) that receives all events
• Extract interfaces from PublisherQueue and AttributePublishQueue
• Support null event detectors in DataPointEventType
• Make the Docker tag configurable via a Maven property
• Add the Chronicle BOM, Chronicle Map module will now use version 2.24ea18 (needs testing)
• MySQL connector was updated to version 8.0.32 as the older version had an incompatible protobuf dependency (needs testing)
