ThingsBoard IoT Gateway

Minor release of ThingsBoard IoT Gateway.

This release contains part of planned improvements for BACnet connector, fixes for bugs and some features.

BACnet connector contains new feature - automatic device discovering, based on broadcasts and data mapping. It is added in beta mode and may work slow now, expecting to improve this in next release. To try it - you can set host to * and port to * - it is an equivalent for global broadcast request.
To automatically map values to time series or attributes - you need to set "*" instead of [] in advanced configuration for BACnet connector.
BACnet connector with using broadcasts in Docker can work only in Linux OS, also you need to set network_mode:host in docker-compose.yml file. In other OS, if you want to use broadcasts - we recommend to use different setup options.

OPC-UA connector has fixes, for attribute updates and RPC, now you can use paths instead of identifiers to send RPC requests and attribute updates to OPC-UA servers.
Service get RPC was improved for OPC-UA connector, you can read current value from node, using attribute or time series key. Example of usage:
Let's assume you have attribute key configuration for device. Attribute key name is "valve1state".
RPC to device to get current value from the node looks like:
get valve1state
In the next release we are going to extend this functionality to have ability to write values to the node in the same way.
