Description

ViewFsOverloadScheme should be able to read mount-table.xml configuration from remote servers.
Below are the discussed options in design doc:

1. XInclude and HTTP Server ( including WebHDFS)
2. Hadoop Compatible FS (HCFS)
   a) Keep mount-table in Hadoop compatible FS
   b)Read mount-table from Hadoop compatible FS using Xinclude

We prefer to have 1 and 2a. For 1 we don't need to modify any code. So, this Jira can cover 2a.
