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.

3cf90a4dff v3rpc: do not send closing event 
When a watch stream closes, both of the watcher.Chan and closec
will be closed.

If watcher.Chan is closed, we should not send out the empty event.
Sending the empty is wrong and waste a lot of CPU resources.
Instead we should just return.
