This adds tracking for how long a peer has been online, while NOT reestasblishing a channel through the use of ChannelReestablish P2P messages. If a peer has been online for a long time without sending a ChannelReestablish, this is a hint that perhaps their end of the channel is borked and cannot be used anymore. One situation where this occurs is when the peer restores its node without use of an SCB file, in which case the ChannelReestablish messages the local peer sends are ignored and the remote peer does not reply with their own ChannelReestablish.
This exposes the recently introduced per-channel total channel reestablish wait time through the ListChannels RPC interface. This is a useful debug feature for users.
This adds automation for closing channels that haven't been reestablished for some time using the recently introduced metric. Channels with peers that have been online for some time but which have NOT been reestablished though the use of ChannelReestablish messages are good candidates for being force closed, because it is likely the remote peer has lost the ability to use them. Given that the metric tracks the total time across restarts and only while the remote peer is online, we use a default of 72h for the threshold to auto close the channel. This should be a reasonable compromise between not closing too fast on hubs (that are online 24/7) and ephemeral nodes (that may be online only for an hour or two a day). A config parameter is added to control the threshold time used for autoclosing and an itest is added that asserts the correct behavior.
This adds the short channel id to the ListChannels() response in a string format. This is useful when debugging and searching logs and the int version is not useful for that.
