Reduce Web home page reliance on ufs mount points

Description

Web home page get under filesystem total/used capacity of root mount point. However, it gets the whole mount table. When we generate the mount point info of a mount point, we call `ufs.getSpace()`. and `ufs.getSpace` is only implemented in hdfs. If hdfs mount points are unavailable, the web ui home page may have some latency issue.
