* update docs * plugins: use plugin specific logging Hooking up pkg/log also changed NewWithPlugin to just take a string instead of a plugin.Handler as that is more flexible and for instance the Root "plugin" doesn't implement it fully. Same logging from the reload plugin: .:1043 2018/04/22 08:56:37 [INFO] CoreDNS-1.1.1 2018/04/22 08:56:37 [INFO] linux/amd64, go1.10.1, CoreDNS-1.1.1 linux/amd64, go1.10.1, 2018/04/22 08:56:37 [INFO] plugin/reload: Running configuration MD5 = ec4c9c55cd19759ea1c46b8c45742b06 2018/04/22 08:56:54 [INFO] Reloading 2018/04/22 08:56:54 [INFO] plugin/reload: Running configuration MD5 = 9e2bfdd85bdc9cceb740ba9c80f34c1a 2018/04/22 08:56:54 [INFO] Reloading complete * update docs * better doc
