M. J. Fromberger 211ef67222 tailcfg,ipn/ipnlocal: regulate netmap caching via a node attribute (#19117) ... Add a new tailcfg.NodeCapability (NodeAttrCacheNetworkMaps) to control whether a node with support for caching network maps will attempt to do so. Update the capability version to reflect this change (mainly as a safety measure, as the control plane does not currently need to know about it). Use the presence (or absence) of the node attribute to decide whether to create and update a netmap cache for each profile. If caching is disabled, discard the cached data; this allows us to use the presence of a cached netmap as an indicator it should be used (unless explicitly overridden). Add a test that verifies the attribute is respected. Reverse the sense of the environment knob to be true by default, with an override to disable caching at the client regardless what the node attribute says. Move the creation/update of the netmap cache (when enabled) until after successfully applying the network map, to reduce the possibility that we will cache (and thus reuse after a restart) a network map that fails to correctly configure the client.
