M. J. Fromberger 9f48567bf1 ipn/ipnlocal,wgengine/magicsock: add basic counters for cached peer connectivity (#19699) ... Add new clientmetric counters for establishing contact with peers while using cached network map data. To do this, instrument the magicsock.Conn with a bit to indicate whether its peer data came from a cached netmap. If so, there are two conditions we will count as establishing connectivity to a peer: - Receipt of a CallMeMaybe from a peer via disco. - Establishing a valid endpoint address for a peer. In vmtest, add Env.ClientMetrics to scrape metrics from the specified node. Use this to check that counters were updated in caching tests.
