Joshua M. Boniface 2a637c62e8 Port provisioner scripts to updated framework 
Updates all the example provisioner scripts to use the new functions
exposed by the VMBuilder class as an illustration of how best to use
them.

Also adds a wrapper fail() handler to ensure the cleanup of the script,
as well as the global cleanup, are run on an exception.

###############################################################################
# This script provides an example of a PVC provisioner script. It will create a
# standard VM config, download and configure pfSense with Packer, and then copy
# the resulting raw disk image into the first RBD volume ready for first boot.
#
# This script has 4 custom arguments and will error if they are not properly configured:
# pfsense_wan_iface: the (internal) interface name for the WAN, usually "vtnet0" or similar
# pfsense_wan_dhcp: if set to any value (even empty), will use DHCP for the WAN interface
# and obsolete the following arguments
# pfsense_wan_address: the static IPv4 address (including CIDR netmask) of the WAN interface
# pfsense_wan_gateway: the default gateway IPv4 address of the WAN interface
#
# In addition, the following standard arguments can be utilized:
# vm_fqdn: Sets an FQDN (hostname + domain); if unspecified, defaults to `vm_name` as the
# hostname with no domain set.
#
# The resulting pfSense instance will use the default "root"/"pfsense" credentials and
# will support both serial and VNC interfaces; boot messages will only show on serial.
# SLAAC will be used for IPv6 on WAN in addition to the specified IPv4 configuration.
# A set of default-permit rules on the WAN interface are included to allow management on the
# WAN side, and these should be modified or removed once the system is configured.
# Finally, the Web Configurator is set to use HTTP only.
#
# Other than the above specified values, the new pfSense instance will be completely
# unconfigured and must then be adjusted as needed via the Web Configurator ASAP to ensure
# the system is not compromised.
#
# NOTE: Due to the nature of the Packer provisioning, this script will use approximately
# 2GB of RAM for tmpfs during the provisioning. Be careful on heavily-loaded nodes.
# This script can thus be used as an example or reference implementation of a
# PVC provisioner script and expanded upon as required.
# *** READ THIS SCRIPT THOROUGHLY BEFORE USING TO UNDERSTAND HOW IT WORKS. ***
# A script must implement the class "VMBuilderScript" which extends "VMBuilder",
# providing the 5 functions indicated. Detailed explanation of the role of each
# function is provided in context of the example; see the other examples for
# more potential uses.
# Within the VMBuilderScript class, several helper functions are exposed through
# the parent VMBuilder class:
# self.log_info(message):
# Use this function to log an "informational" message instead of "print()"
# self.log_warn(message):
# Use this function to log a "warning" message
# self.log_err(message):
# Use this function to log an "error" message outside of an exception (see below)
# self.fail(message, exception=<ExceptionClass>):
# Use this function to bail out of the script safely instead if raising a
# normal Python exception. You may pass an optional exception class keyword
# argument for posterity in the logs if you wish; otherwise, ProvisioningException
# is used. This function implicitly calls a "self.log_err" with the passed message
# Within the VMBuilderScript class, several common variables are exposed through
# the parent VMBuilder class:
# self.vm_name: The name of the VM from PVC's perspective
# self.vm_id: The VM ID (numerical component of the vm_name) from PVC's perspective
# self.vm_uuid: An automatically-generated UUID for the VM
# self.vm_profile: The PVC provisioner profile name used for the VM
# self.vm_data: A dictionary of VM data collected by the provisioner; as an example:
# {
# "ceph_monitor_list": [
# "hv1.pvcstorage.tld",
# "hv2.pvcstorage.tld",
# "hv3.pvcstorage.tld"

# WARNING:
#
# For safety reasons, the script runs in a modified chroot. It will have full access to
# the entire / (root partition) of the hypervisor, but read-only. In addition it has
# access to /dev, /sys, /run, and a fresh /tmp to write to; use /tmp/target (as
# convention) as the destination for any mounting of volumes and installation.
# Of course, in addition to this safety, it is VERY IMPORTANT to be aware that this
# script runs AS ROOT ON THE HYPERVISOR SYSTEM. You should never allow arbitrary,
# untrusted users the ability to add provisioning scripts even with this safeguard,
# since they could still do destructive things to /dev and the like!
# This import is always required here, as VMBuilder is used by the VMBuilderScript class.
