* Updated document vmware_readme.rst to mention VLAN networking

* Corrected docstrings as per pep0257 recommentations.
* Stream-lined the comments.
* Updated code with locals() where ever applicable.
* VIM : It stands for VMware Virtual Infrastructure Methodology. We have used the terminology from VMware.  we have added a question in FAQ inside vmware_readme.rst in doc/source
* New fake db: vmwareapi fake module uses a different set of fields and hence the structures required are different. Ex: bridge : 'xenbr0' does not hold good for VMware environment and bridge : 'vmnic0' is used instead. Also return values varies, hence went for implementing separate fake db.
* Now using eventlet library instead and removed io_utils.py from branch.
* Now using glance.client.Client instead of homegrown code to talk to Glance server to handle images.
* Corrected all mis-spelled function names and corresponding calls. Yeah, an auto-complete side-effect!
