Changes the dimensionsFilters property to dimensionsFilter in the Azure Monitor Datasource's AzureMonitor service to make what is sent to match the saved model.

Before this, the property that the backend was expecting was not available in the case of alerting, where the stored model is fetched.

This also fixes a panic when there is a dimension alias but no dimension
