Bug Fixes

• Only index spans if field mapping was created by stagemonitor #347
• SoapHandlerTransformer previously required excessive type hierarchy matching which could lead to OutOfMemoryErrors
• Remove credentials from URLs when making HTTP calls. This way the credentials don't show up in Exception messages. The credentials are now only transmitted via the Authorization header.
• ES credentials exposed in exception log #362

Improvements

• Added support for Elasticsearch 6.x
