appc,*: publish events for route updates and storage (#17392)

Browse Source 
Add and wire up event publishers for these two event types in the AppConnector.
Nothing currently subscribes to them, so this is harmless. Subscribers for
these events will be added in a near-future commit.

As part of this, move the appc.RouteInfo type to the types/appctype package.
It does not contain any package-specific details from appc. Beside it, add
appctype.RouteUpdate to carry route update event state, likewise not specific
to appc.  Update all usage of the appc.* types throughout to use appctype.*
instead, and update depaware files to reflect these changes.

Add a Close method to the AppConnector to make sure the client gets cleaned up
when the connector is dropped (we re-create connectors).

Update the unit tests in the appc package to also check the events published
alongside calls to the RouteAdvertiser.

For now the tests still rely on the RouteAdvertiser for correctness; this is OK
for now as the two methods are always performed together.  In the near future,
we need to rework the tests so not require that, but that will require building
some more test fixtures that we can handle separately.
