Sherry Guo commented on SLIDER-469:
-----------------------------------

I worked on a patch for this.  I went with using "+" and "-" to indicate relative numbers of instances instead of a new command argument.  Please help review and let me know if additional tests are needed.  Thanks.

> reported:
> bq. Currently Slider cli has option of flexing but that option takes total no of instances.
> bq. But instead we should also introduce flex up or down option.
> {code}
> ./slider flex <up/down> mycl2 --component MEMCACHED 2
> {code}
> bq. This will increase the memcached containers by 2 [ instead of total two ].
