Suppress tracing on NotFound response

[MarkMpn]

I commonly use ReadItemStreamAsync to try to get a value which might or might not exist. Although this method doesn't throw an exception if the item doesn't exist, it still logs an error via the trace listener, which fills up my logs and makes actual errors harder to find. My logs quickly fill up with entries like:

Operation will NOT be retried. Current attempt 0, Status Code: NotFound

I'd like an option to filter errors before they are logged so I can ignore these errors without turning off all error logging as I don't want to lose other error logs in case of more serious problems.

Is there something I can use within the existing code to achieve this?

Seems the trace is coming from

azure-cosmos-dotnet-v3/Microsoft.Azure.Cosmos/src/ResourceThrottleRetryPolicy.cs

Lines 55 to 58 in 0d4e93f

	DefaultTrace.TraceError(
	"Operation will NOT be retried. Current attempt {0}, Status Code: {1} ",
	this.currentAttemptCount,
	dce.StatusCode);

This trace should not be a TraceError but rather a TraceVerbose.

azure-cosmos-dotnet-v3/Microsoft.Azure.Cosmos/src/ResourceThrottleRetryPolicy.cs

Lines 84 to 87 in 0d4e93f

	DefaultTrace.TraceError(
	"Operation will NOT be retried. Current attempt {0}, Status Code: {1} ",
	this.currentAttemptCount,
	cosmosResponseMessage?.StatusCode);

Should also need to be adjusted.

@rinatmini Could you take a look? Should be a small/straightforward change.
