LedgerRetrySpec
class LedgerRetrySpec @InternalWowApi constructor(val maxRetries: Int, val initialBackoff: String, val claimTtl: String, val applied: Boolean = false)
The retry spec a parked entry is retried by: at most maxRetries automatic retries, the first initialBackoff after the failure, each claiming the entry for claimTtl (durations); applied when an operator applied it, rather than the subscription's.
Fields may be added: construct it with of; the constructor is internal to Wow.
