Sample corrections for M14

Browse Source 
* Update node configurations to match changes to test constants
* Look up notary via RPC in attachment demo rather than using the static identity to ensure the correct key is resolved
* Use notary service identity instead of legal identity in Bank of Corda demo
* Correct typo in deprecation annotation in CordaRPCOps
* Update from deprecated calls to new equivalents
