Pass OpenTelemetry to SystemAccessControl

[findepi]

This is necessary for SystemAccessControl implementation to participate in tracing. Useful when the implementation does e.g. network communication when performing access control.

Why do you need an instance of OpenTelemetry? Generally, all you need is a properly configured Tracer.

I didn't see how access control needs would be different than those of a connector. I followed ConnectorContext where @electrum added both

trino/core/trino-spi/src/main/java/io/trino/spi/connector/ConnectorContext.java

Lines 31 to 39 in bda3510

	default OpenTelemetry getOpenTelemetry()
	{
	throw new UnsupportedOperationException();
	}
	default Tracer getTracer()
	{
	throw new UnsupportedOperationException();
	}

I couldn't find any authoritative docs or code comments, thus may be drawing wrong conclusions, but both are expected here
https://github.com/airlift/airlift/blob/c55517863fe246f8921b0a03034b0e2f0d7a31c9/http-client/src/main/java/io/airlift/http/client/HttpClientModule.java#L121-L131
and both are later used, if provided.

nit: verify that systemAccessControlName is not empty or null

[findepi]

this is verified by the caller within the class and the method is private
also, empty string is currently valid factory name :)
