Title: Add ability to call other redis commands

This commit adds the ability to get metrics from other redis commands. In particular, I wanted to be able to check the length of a key list (LLEN ). In keeping backward compatibility I called this option "operation". Usage might look like:

```
./check_redis -H -w 20 -c 25 -i -K -o llen
```
This would call `@redis.llen()` and would compare the results to w/c values of 20/25 respectively.

I am open to suggestions/changes if you think something would be better suited in a different way. Thanks for taking a look.
