VPP-899: Run VPP under SELinux

Add an SELinux profile such that VPP can run under SELinux on RPM based
platforms. The SELinux Policy is currently only implemented for RPM
packages, specifically, Fedora, CentOS and RHEL. Doxygen User
Documentation has been included (selinux_doc.md). Once some discussion
on file locations has completed (see vpp-devlist), updates to the Debug
CLI documentation will also need to be updated.

Additional changes:
Patch Set 2:
- Rework selinux_doc.md such that each line is only 80 characters
  instead of each sentence on a line. Made additonal minor chnages
  to the text.
- Update vHost Debug CLI documentation to reflex new socket location.
  Cleaned up some text from when I originally wrote it, to better
  reflex proper use.
- Update exec Debug CLI documentation to be more inline with suggested
  helptext, added text regarding recommended script file location.
- For Debian builds, create the /var/log/vpp/ directory. I don't use
  Debian very much, so please pay extra attention to
  build-data/platforms.mk and build-root/deb/debian/.gitignore.
- Per discussion on VPP call, changed the default log location to
  /var/log/vpp/vpp.log.
- Changed the socket location for vHost in AutoConfig to
  /var/run/vpp/.
Patch Set 3:
- Update selinux_doc.md based on comments.
