1543253bfd scyllatop: differentiate metrics coming from different hosts 
Fix issue #1173.
Previously scyllatop aggregated metrics coming from a cluster with many
hosts so that individual contributions could not be recognized. This is
now changed so that aggregation is also by hostname.

97bb7a35d9 tools/scyllatop: some sensible default metrics 
Previosly if the user did not specify any metrics, scyllatop use
whatever it could find. Now we have some preset defaults which are
probably more interesting.

1cd01cd2ab tools/scyllatop: defend against curses "out of screen bounds" error 
Fixes issue #945 (hopefully)
This issue was probably the result of trying to write outside the
confines of the window. The views.Base class now defends against this.

1f6cac8839 tools/scyllatop: Use 'erase' to clear the screen 
The 'clear' function explicitly clears the screen and repaints it which
causes really annoying flicker. Use 'erase' to make scyllatop more
pleasant on the eyes.
