* New clixon-lib@2020-04-23.yang revision

* Added: stats RPC for clixon XML and memory statistics.
  * Added: restart-plugin RPC for restarting individual plugins without restarting backend.
* xml-stats moved from clixon-config.yang as state data to an rpc `datastats` in clixon-lib.yang
* Experimental: restart_plugin
* Two new plugin callbacks added
  * ca_daemon: Called just after a server has "daemonized", ie put in background.
  * ca_trans_commit_done: Called when all plugin commits have been done.
    * Note: If you have used "end" callback and usign transaction data, you should probably use this instead.
