vshl-capabilities:
This API is responsible for brokering capbilities related messages from voiceagents to apps and vice versa. Verbs exposed are navigation/publish navigation/subscribe phonecontrol/publish phonecontrol/subscribe playbackcontroller/publish playbackcontroller/subscribe guiMetadata/publish guiMetadata/subscribe This API exposes publish and subscribe methods for all the speech framework domains/capabilities. For eg. navigation, phonecontrol etc. This API is used by apps and low level voice agent binding to subscribe and publish these capability messages whenever applicable. This specific commit is for vshl-capabilities API. Change-Id: I822c2e8589e39574d707a7c199bea91a686dced7 Signed-off-by: Naveen Bobbili <nbobbili@amazon.com>
