Cloud platform support

Kubernetes

OneAgent on Kubernetes will consider proper alerting when a pod is marked for termination
Detectable SSL errors are distinguished (untrusted, expired, hostname not matching) and presented in the Dynatrace UI.

Cloud Foundry

Connecting to a CF foundation from the Dynatrace UI results in better login-failure handling. There is now a limit on the number of retries that can be attempted following authenticaion errors (5 per hour). This is configurable in custom.properties using the keys lockoutAfterFailures and countFailuresWithinSeconds.
Detectable SSL errors are distinguished (untrusted, expired, hostname not matching) and presented in the Dynatrace UI.
