Make the vulnerabilitiy parser as an option in initialize_vFense.py

[linuxdynasty]

Currently the XML, XLS and HTML parser for CVEs, Windows, and Ubuntu happen during the initialize phase, maybe what we should do is add it as an option in the initialize_vFense script that will parse all the data and store it in json on disk. Then once the main initialize function runs, it will just load the Json data into the database. This will make the initialize portion utilize less ram as a whole. Though it will be mandatory to run that option before running the main initialize portion of the script.

After speaking with @humchacon yesterday, we both agreed on the following.

• Create a new github repository 'vulnerabilities' https://github.com/vFense/vulnerabilities
• Create a job that will check the respective vendors and update the repository
• This will decrease the amount of memory needed during the initialization phase as well as the operational phase.
• The vFense server will always check the repository for the latest vulnerabilities and if the repository is down or out of date, it will then pull from the respective vendors.
