[FEATURE REQ] Add possibility to disable/enable StatsbeatModule.

**Is your feature request related to a problem? Please describe.**
Customer may disable collecting telemetry in our product by settings panel. After that, no network traffic related to telemetry should happen. Customer should not be forced to restart product after disabling telemetry. AzureMonitorExporterBuilder.initializeIfNot creates and start StatsbeatModule without giving possibility to call shutdown on instance of this StatsbeatModule.

**Describe the solution you'd like**
Add to ConfigProperties the option "applicationinsights.statsbeat.enabled" similar to existing one "applicationinsights.live.metrics.enabled", which willl be handled in initializeIfNot and will allows to not use statsbeat. We use only Log events and this statsbeat is not usefull for us.
