Xiang Li ee0b3f42ed *: rename watcher to watchStream
Watcher vs Watching in storage pkg is confusing. Watcher should be named
as watchStream since it contains a channel as stream to send out events.
Then we can rename watching to watcher, which actually watches on a key
and send watched events through watchStream.

This commits renames watcher to watchStram.
