clixon/test/test_nacm_default.sh
Olof hagsand c64878fd4a * RESTCONF configuration is unified and moved from clixon-config.yang to clixon-restconf.yang 
* Except `CLICON_RESTCONF_DIR` which remains in clixon-config.yang due to bootstrapping
    * -d <dir> option removed
  * This applies to both evhtp and fcgi RESTCONF
    * Both can also read config from backend, and be started from backend
  * You may need to move config as follows (from clixon-config.yang to clixon-restconf.yang)
    * CLICON_RESTCONF_PRETTY -> restconf/pretty
    * CLICON_RESTCONF_PATH -> restconf/fcgi-path
