Rename util scripts to avoid collisions.

All the util scripts now have a prefix of pbench-.

#64

[ndokos]

We can add symlinks from the old names to the new names for backwards compatibility - and we can do that in the RPM rather than adding them to the repo. After a suitable period,
and with enough warning, we can get rid of them for a future release. Thoughts?
If that's acceptable, we can include this PR in the next release.

[atheurer]

Not sure how I feel about symlinks. I would expect that people would just continue to use the old names, unless there's a huge warning every time they use the old name.

In this case, I am not in favor of backward compatibility. If they need that, I would suggest that use the existing release. This is a sufficiently large problem for other reasons that I do not think trying to maintain backward compatibility is worth it here.

The travis build is borked - I'm looking into what needs to be done to fix it:

$ sudo pip3 install configtools elasticsearch

Re: backward compatibility - we could add a script that would take an old name, issue a big fat warning and call the new name, as Andrew suggests. If we don't provide BC, we are basically saying that if you want the new release, you have to go modify your scripts first. It seems to me that the transition would be harder that way.

[atheurer]

As long as we have the warning, I think that will be ok.
We will release another version next month anyway, and hopefully that one removes the older names.
