Backport
This PR is auto-generated from #16776 to be assessed for backporting due to the inclusion of the label backport/1.15.
The below text is copied from the body of the original PR.
Description
Currently, if an acceptor peer deletes a peering the dialer's peering will eventually get to a "terminated" state. If the two clusters need to be re-peered the acceptor will re-generate the token but the dialer will encounter this error on the call to establish:
This is because in
exchangeSecret().GetDialAddresses()
we will get an error if fetching addresses for an inactive peering. The peering shows up as inactive at this point because of the existing terminated state.Rather than checking whether a peering is active we can instead check whether it was deleted. This way users do not need to delete terminated peerings in the dialing cluster before re-establishing them.
