Release v1.2.0

[mateuszrzeszutek]

This release uses OpenTelemetry Instrumentation for Java version 1.4.0. If you want to extend the instrumentation manually, we suggest using the OpenTelemetry Java API version 1.4.1. Please consult the release notes linked above for upstream changes.

🗒 General notes

• OpenTelemetry Java SDK has been updated to version 1.4.1.
• OpenTelemetry Instrumentation for Java has been updated to version 1.4.0.

🌟 Enhancements

• We have added instrumentation for HikariCP and Tomcat JDBC connection pools. The agent now collects and exports metrics for both JDBC connection pools.
• You can now set the service name using the OTEL_SERVICE_NAME environment variable and the otel.service.name system property. This removes the need of using OTEL_RESOURCE_ATTRIBUTES to set the service name.
