Including Exception and EventId in Lambda Logger messages

[karpikpl]

Issue #, if available:
Microsoft.Extensions.Logging interface supports logging EventId and Exceptions, but when LambdaLogger is configured, those objects are not saved in CloudWatch.

Sample scenario:

logger.LogError(LoggingEvents.DbOperationError, ex, $"SelectData: {spName} SqlException Number: {se.Number} Sql Parameter: {spc}");

The natural expectation is that both Logging Event and Exception will be available in CloudWatch, which is not the case.

Description of changes:
I've included 2 new settings on Lambda Logger Options to enable EventId and Exceptions logging.
