Handle status and error messages in the reponses from the KOMBIT ContextHandler

[janhalen]

To get visibility into the state of the communication with the KOMBIT SAML ContextHandler the SAML responses needs to be collected and passed on using standard methods.

• Log responses and errors from KOMBIT SAML Contexthandler
• Make the messages available for standard observability tools to collect and process

OpenTelemetry would be a fitting, modern method of handling the status messages.
