Dynatrace extension framework upgrade notice

Starting with Dynatrace OneAgent and ActiveGate version 1.231, we are upgrading the Extension Framework (also referred to as the plugins framework) from Python 3.6 to Python 3.8.

Consequences: Some Dynatrace extensions running in your environment may stop working and require redeployment of a new version prepared for Python 3.8.
Symptoms:
- No data is provided for affected metrics on dashboards, alerts, and custom device pages populated by the affected extension metrics.
- Extension logs display errors. Most often this will manifest itself as Python ModuleNotFoundError in the PluginAgent log.
- Sometimes the Python virtual machine crashes.
Impact: This issue affects only those extensions that use native libraries called from Python code distributed with the extension.
