   Regarding 
   ```
   get docId for the given action'name and version parameter, if no version is specified, the latest "published" version will be choosed, and if version is provided, related version will be replaced in CouchDB, so users can update an action in place
   if there is a docId returned in step1, fetch action using that docId, and created a new action based on old action and user's input, save it to database
   if there is no docId, just created a new action based on user's input and save it
   ```
   Let's assme for exist hello action with 3 versions: `hello@0.0.1` and `hello@0.0.2`, and `hello@0.0.3`,
    `hello@0.0.1` and `hello@0.0.2` are old action, `hello@0.0.3` is the latest action,
   
   It seems user can update old action (e.g. `hello@0.0.1` and `hello@0.0.2`) when pass version parameter?
   
   For my understanding, for create/update, seems pass action name only is enough.
   * create
     -  If exist action in db, need to remind user that the action with latest version already exists
     -  If does't exist in db, create the action with init version
   * update
     - If exist action in db, create the action with `current verstion` + 1
     - if doesn't exist action in db, create the action with init version (this is same as create)
