Review request for accumulo and Bill Slacum.


Bugs: ACCUMULO-2850
    https://issues.apache.org/jira/browse/ACCUMULO-2850


Repository: accumulo


Description
-------

New scripts for the memory stress test make it easy to start and stop multiple reader and
writer processes, in a manner similar to continuous ingest. See the updated README.md for
information on how the scripts are used.

(This patch builds on top of ACCUMULO-2849, but could be fixed and submitted independently.)

General guidance for reviewers:
* The top README.md content was reformatted with line breaks, but minimal edits to content.
Most of the real change is the new content after the first section.
* Variables formerly set in reader.sh and writer.sh moved to a common stress-env.sh that gets
sourced.
* The readers and writers files are for listing hosts that should run scan and write processes
(resp.).
* The start- and stop- scripts manage starting readers and writers across the cluster.
