/**
* Similar to [sendAndReceive] but also instructs the `payload` to be redelivered until the expected message is received.
*
* Note that this method should NOT be used for regular party-to-party communication, use [sendAndReceive] instead.
* It is only intended for the case where the [otherParty] is running a distributed service with an idempotent
* flow which only accepts a single request and sends back a single response e.g. a notary or certain types of
* oracle services. If one or more nodes in the service cluster go down mid-session, the message will be redelivered
* to a different one, so there is no need to wait until the initial node comes back up to obtain a response.
