Unsupported text Content-Type Type QuickPulsePingSender warnings in logs

Start with QuickPulsePingSender and trace the 503 response through JacksonAdapter and HttpResponseBodyDecoder, using the stack trace as the entry point. Reproduce against westeurope.livediagnostics.monitor.azure.com and compare with centralus; done means an Azure 503 no longer produces the unsupported text Content-Type parsing warning.

Expected behavior

No parsing error.

Actual behavior

We observe some errors:

LoggerName = com.azure.monitor.opentelemetry.autoconfigure.implementation.quickpulse.QuickPulsePingSender

Message = Unsupported text Content-Type Type: class com.azure.monitor.opentelemetry.autoconfigure.implementation.quickpulse.swagger.models.ServiceError
