simplified appendLimit implementation

AppendLimit is now set to max value by default. This simplifies the code
while keeping most of the feature functionality. This change increases
report version and will cause older report to be deleted.

Tested:
- AppendLimit is set by default to max value
- Telemetry features are working as expected
