Check to start a trace with the given identifier.
This does a lookup in the background to the global TracyWeb.Coordinator process, to see whether the given definition id exists. When it does, it will start tracing the current process.
Optionally, a session id can be passed in to override the otherwise auto-generated session id.
metadata can be a function which will be called when the tracing
is started. It needs to return a map which will contain the trace
metadata.
