[Vis Augmenter] Support filtering of the feature based on the selected data source

[ohltyler]

Data sources may have different configurations / compatibility issues that would not make them eligible for the feature. For example, suppose the user is running OSD with AD and Alerting, which are both integrated with Vis Augmenter. When selecting a datasource, if that datasource does not have these plugins installed or available, we should hide the AD & Alerting options for that visualization.
