Scrapy Cluster Utils Packaging

[madisonb]

It would be nice if we could bundle the utils folder into its own package so that we no longer need symlinks or to duplicate code when scrapy cluster is deployed across multiple machines.

This issue should also cover the documentation of said sc-utils package and getting it on pypi.

Starting work on this. The plan is to package up all the utils under the sc-utils name and change the code to import each module as needed. For example, from sc-utils import log_factory.

The packaging is complete with pull request #21. Would like to host scutils on PyPi so that it doesn't have to be built manually. Can do the PyPi packaging as part of this issue or open a new one.

Green light to put it up, just reference that the documentation for 0.0.1 is not quite ready yet and will be released with SC 1.1.

Do it as apart of this issue, and update the Readme, reqs.txt, etc for better installation instructions.

This is up on PyPi now. pip install scutils will install the module.
