[native] introduce addKeyserverActionType

Summary:
This diff introduces the `ADD_KEYSERVER` redux action type as well as the `AddKeyserverPayload` type that we will need for this redux action. Since at this moment we are only adding and persisting any newly added keyserver to the keyserver redux store, we don't need start, success, fail action types since we are not making any calls to an endpoint
