Update diskstats for linux kernel 4.19 (#1109)

Browse source 
The format of /proc/diskstats is changing in linux-4.19 to include some
additional fields.  See: https://www.kernel.org/doc/Documentation/iostats.txt

* collector/diskstats: use constants for some hard coded strings
* collector/diskstats: update diskstats for linux-4.19
* collector/diskstats: remove kernel doc url from individual metrics
