Add Some Wrapper Flows To Facilitate Shell Access

[opticyclic]

I can create an account from the shell like this:

flow start CreateAccount name: TestAccount

However, it seems impossible to share that account with another node from the shell due to the complex objects in the constructor:

flow start ShareAccountInfo
No matching constructor found:
- [accountInfo: StateAndRef<com.r3.corda.lib.accounts.contracts.states.AccountInfo>, recipients: List<Party>]: missing parameter accountInfo

It would be useful to add extra flows that wrapped the normal flows so they can be called from the command line.

e.g. in this case it would be easier to pass the UUID as a String and a single Party in the same way that the Service works

fun shareAccountInfoWithParty(accountId: UUID, party: Party): CordaFuture<Unit>
