add --pid-file-dir option for setting location of pid file.

Option for changing pid location. It's only enable when --daemon option is specified.

Thank you for the PR @suzuken. I have looked it through and it seems to be missing some parts to work. See my inline comments above.

I do think that this is a great idea and it would be great to get it implemented and merged.

@sebdah Thank you for your quick reply and review. I'm not familiar with scripting in Python, so grad to see your commend.

Fixed some codes and add file for adding options. By the way, the docs is automatically generated by script and should I do this in my hand? If so, I'll add it on this PR.

Thanks! I will fix merging with the latest code base and also write the docs. I'll also make a few changes to make the command line this work (there's a global option that must be set and referenced properly).

Will fix that and update here soon.

Thanks again @suzuken! I have now fixed the mentioned things and the code has been merged to the develop branch, meaning that it will be included in the next release of Dynamic DynamoDB. I intend to release the next version sometime within this week.
