Short: "start a file server that points to a master server",

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/

|
|
|
Current <fullpath~fileid> mapping metadata store is local embedded leveldb.
|
|
It should be highly scalable to hundreds of millions of files on a modest machine.
|
|
|
|
Future we will ensure it can avoid of being SPOF.
