lntest+lnwallet: add AddressInfo to WalletController

Browse Source 
We need to be able to query the watch-only wallet about a public key
when trying to sign with a key that we don't know the family or index
of. The easiest way to do that is to leverage the wallet's address index
to query the derivation path for a public key.
To give the RPC wallet access to that functionality, we need to expose
the method on the WalletController interface.
