Long: `start a file server which accepts REST operation for any files.
//create or overwrite the file, the directories /path/to will be automatically created
POST /path/to/file
//get the file content
GET /path/to/file
//create or overwrite the file, the filename in the multipart request will be used
POST /path/to/
//return a json format subdirectory and files listing
GET /path/to/
The configuration file "filer.toml" is read from ".", "$HOME/.seaweedfs/", "/usr/local/etc/seaweedfs/", or "/etc/seaweedfs/", in that order.
If the "filer.toml" is not found, an embedded filer store will be craeted under "-defaultStoreDir".
The example filer.toml configuration file can be generated by "weed scaffold -config=filer"
