ICS4: Handle removing of upgrade information in `ChanCloseCofirm` #1078

Closed colin-axner closed 5 months ago

colin-axner commented 6 months ago

A channel may be closed at any moment either by an IBC application initiating the closure or by a packet timing out on an ORDERED channel. This may occur at any step in the channel upgrade process. The specs should be updated to ensure auxiliary state is not leftover when a channel transitions to CLOSED during a channel upgrade
