Add Nagios logging capabilities

[JasonYao]

Piece this together later on utilising these docs: Nginx + nagios 3: http://johan.cc/2012/02/06/nagios-nginx/ Ubuntu + nagios 4 (LAMP): https://www.digitalocean.com/community/tutorials/how-to-install-nagios-4-and-monitor-your-servers-on-ubuntu-14-04

Other possibility: utilise monit instead of nagios monit pros:

• easy setup time
• Only one node, so perfect for use case (multi-node is possible, but goes against the easy setup time)
• Has documentation

monit cons:

• Developer experience, as Nagios seems much more established.

Nagios pros:

• Extensibility
• Has all the features of monit + more

Nagios cons:

• Setup can be a bitch without experience

Weight: whether to use this as a learning experience for nagios, or just get quick monitoring with monit

In order to have the nagios subdomain available at nagios.skullhouse.nyc, TLS certs need to be generated, since this is information that should not be sniffed.

Recommendation is to incorporate Let's encrypt, such that all keys are automatically set

Afterwards, write up documentation, do the httpw protection file, and whatever else i'm forgetting. Combine stuff between the two links here and here
