[docker] Cleanup, minor fixes, formula bump

* ship prebuilt salt master conf for better readability:
  - enable x509.sign_remote_certificate (for prx VCP nodes);
* refactor Salt master CA handling:
  - preinstall `salt_minion_dependency_packages` and
   `salt_minion_reclass_dependencies` inside docker image;
  - persistent /etc/pki;
  - run salt.minion on cfg01 to generate master keys;
* bump container formulas to 1 Sep 2018 versions or newer:
  - inject date into Docker makefile, forcing a fresh fetch of all
    salt formulas from upstream git repos;
* workaround broken salt-formula-designate's meta/sphinx.yml:
  - the DEB package version of salt-formula-designate uses `cmd.shell`
    to query dpkg on the minion, while the git repo version still
    uses `cmd.run`, running into parsing issues;
  - temporarily disable sphinx metadata generation for designate until
    upstream git repo syncs with the DEB version;
* upstream: salt-formula-salt AArch64 salt.control.virt support:
  - retire salt-formula-salt git submodule and related patches;
* skip installing reclass distro package (already installed via pip
  inside the container);
* limit initial pillar_refresh call to nodes on jumphost;
* remove unused salt-formula-nova git submodule;

-Subject: [PATCH] libvirt xml: pass loader, virt machine, cpu mode
-
-- libvirt xml: pass loader param to vm
-  Based on upstream commit [1].
-- libvirt xml: pass virt machine type
-- libvirt xml: pass cpu mode to vm
-- virt module: Allow NVRAM unlinking on DOM undefine
-  UEFI-enabled VMs usually have pflash (NVRAM) devices attached,
-  which require one additional libvirt flag to be passed at 'undefine'.
-  This is usually the case for AArch64 (arm64) VMs, where AAVMF (AA64
-  UEFI) is the only supported guest bootloader.
