inline and repackaged the required external library (jedis, commons-pool) - avoid library conflicts

[andirdju]

what do you think about inlining and repackaging the jedis dan commons-pool dependency?
so it won't have conflict with users using different version of those library.

we can do this using maven-shade-plugin. no changes to the code, just pom setup.

I'll create a pull request for it if you think that's useful.
