feat: configure trace level #71

Closed sissbruecker closed 2 years ago

sissbruecker commented 2 years ago

Description

Allows to configure a global trace level option that instrumentations can check for whether they should add some detail to a trace or not. The option supports three levels minimum, default, maximum. The default is default. The option can be changed using any of the configuration mechanism supported by OpenTelemetry, for example environment variables or system properties. For example, to change the trace level with a system property, add the following argument to the java process: -Dotel.instrumentation.vaadin.trace-level=maximum.

This PR is only intended to add the basic option mechanism, and adapts the UidlRequestHandlerInstrumentation to demonstrate its use. The remaining instrumentations will be changed in a separate PR.
