directory structure change to work with glide

glide has its own requirements. My previous workaround caused me some
code checkin errors. Need to fix this.

+
+  If uploading a list of files:
+  It uses consecutive file keys for the list of files.
+  e.g. If the file1 uses key k, file2 can be read via k_1
+
+  If uploading a whole folder recursively:
+  All files under the folder and subfolders will be uploaded, each with its own file key.
+  Optional parameter "-include" allows you to specify the file name patterns.
+
+  If any file has a ".gz" extension, the content are considered gzipped already, and will be stored as is.
+  This can save volume server's gzipped processing and allow customizable gzip compression level.
+  The file name will strip out ".gz" and stored. For example, "jquery.js.gz" will be stored as "jquery.js".
+
+  If "maxMB" is set to a positive number, files larger than it would be split into chunks and uploaded separatedly.
+  The list of file ids of those chunks would be stored in an additional chunk, and this additional chunk's file id would be returned.
