Move ClientSetup and ServerSetup are closely associated with the RSocketFactory implementations. Moving them into core where they are used from breaks a package cycle between resume and internal. ClientSetup is straight-forward and folds easily into DefaultClientRSocketFactory. ConnectionUtil is closely associated with ServerSetup and has been folded into it.

MissingLeaseException is moved to the lease package next to the contracts it is declared in breaking a cycle between lease and exceptions. This is an API breakage but I the impact should be minor (none? the chances of something handling it explicitly) and hence an acceptable trade-off.

Replaces (now deprecated) RSocketException from the exceptions package which can lead to cycles (e.g. with frame package). Other minor refinements: - error code validation - shared errorCode() implementation - error code in toString() - avoid NPE for null message, it's better to keep the original exception and null is allowed by getMessage().

can we use ErrorType.APPLICATION_ERROR here. In any case, we have ref to ErrorType

Yes, indeed, this should be a constant. I've suggested a further change to use the constants from ErrorFrameFlyweight.

This change deprecates ErrorType as the same constants are already declared in ErrorFrameFlyweight and there is hierarchy of exceptions with one exception per error code. Signed-off-by: Rossen Stoyanchev <rstoyanchev@pivotal.io>

This resolves package cycles between:
lease-internaldue toClientSetupandServerSetup(both related to leasing).exception-leasedue to references betweenMissingLeaseExceptionandLease.exception-framedue to references betweenErrorFrameFlyweightandRSocketException.This is mostly backwards compatible and functionality neutral except for moving
MissingLeasingExceptiontolease. It's unlikely to break anything and a worthwhile trade-off.
