Lists the key rings in the currently-selected location.
public func listKeyRings() throws -> Void
This method lists the key rings in the currently-selected Location.
Calling this method will fire the KeyRingList event once for each key ring, and will also populate the KeyRing* properties.
If there are still more key rings available to list when this method returns, the KeyRingMarker property will be populated. Continue to call this method until KeyRingMarker is empty to accumulate all pages of results in the KeyRing* properties.
The MaxKeyRings configuration setting can be used to control the maximum number of results to return at once.
