Rohit Yadav 85aee8d18d CLOUDSTACK-10013: SystemVM codebase refactorings and improvements
- Refactors and simplifies systemvm codebase file structures keeping
  the same resultant systemvm.iso packaging
- Password server systemd script and new postinit script that runs
  before sshd starts
- Fixes to keepalived and conntrackd config to make rVRs work again
- New /etc/issue featuring ascii based cloudmonkey logo/message and
  systemvmtemplate version
- SystemVM python codebase linted and tested. Added pylint/pep to
  Travis.
- iptables re-application fixes for non-VR systemvms.
- SystemVM template build fixes.
- Default secondary storage vm service offering boosted to have 2vCPUs
  and RAM equal to console proxy.
- Fixes to several marvin based smoke tests, especially rVR related
  tests. rVR tests to consider 3*advert_int+skew timeout before status
  is checked.
