This is related to coredns/coredns#6243 and coredns/coredns#6263, and prerequisite for coredns/coredns#6244.
What does this PR do:
caddy.Instancewith a new fieldConfigDigest, and populate this with a digest of the parsed configuration content (which then includes imported sources); this happens incaddy.ValidateAndExecuteDirectives(). In addition, a functioncaddy.ConfigDigest()is added to allow consumers (such as the coredns reload plugin) to calculate that digest value for a givencaddy.Input.plugin.RegisterOrUpdateEventHook()which works like the existingplugin.RegisterEventHook(), but does not panic in case of duplicate registration (instead, just replaces the hook).Note: these two changes are independent from each other, but both are required for the mentioned PR coredns/coredns#6244.
