Major Hayden e57593dfd4 Automate the STIG documentation 
With the upcoming changes to rebase onto the RHEL 7 STIG controls,
there needs to be a new solution for documentation that is easier
to manage and filter. This patch automates the generation of the STIG
control documentation in the following way:

* A Sphinx extension runs early in the doc build process that writes
  all of the individual STIG control docs as well as ToC pages.
* ToC pages are now sorted by severity, tag, and implementation status.
* A giant listing of controls is easier to navigate now.
* Docs are generated from metadata in the /doc/metadata directory. New
  documentation only needs to be added there. (Will explain this in
  the developer notes in a subsequent patch.)

This patch disables ICMPv4 redirects feature on the host. Accepting ICMP redirects has few legitimate uses. It should be disabled unless it is absolutely required.

It is configurable by security_disable_icmpv4_redirects variable. This feature is disabled by default as it can disrupt LXC deployments.

Deployers can skip or enable this task by setting security_disable_icmpv4_redirects to no or yes, respectively.
