Fix volume options

Change I358c414adb49bba9349f30a1190c2f8b90f13d14 had a few issues. Of
note, packer variables can only be strings, even if they get
interpolated to booleans where needed.

Additionally the volume format can only be specified if
use_block_storage is true and we default to false. This means that if
volume storage is being set then the volume format must be set and it
needs to be set to raw!

Finally, the windows builder did not contain all the extra variables
being defined.

Enable selection of instance knobs

We now operate in multiple Openstack clouds (even if from the same
provider) and thus need to properly enable selectability of the region,
availability zone, instance flavor size, and if a volume needs to be
created (and at what size) for builds. We default to our current
standard configuration for Vexxhost Montreal.

If vm_use_block_storage is set true then vm_volume_size will be used
(along with the image_disk_format option which must be "raw"). If it is
false (default) then the volume size and format will be ignored. This is
needed for building on flavors that do not predefine any attached disk
as is the case for all flavors in the SJC cloud for Vexxhost.

Add lf-network note regarding ssh-agents

When building packer images in AWS, I found I wasn't easily able to

my ssh-agent.

Even setting all at once: ssh_agent_auth=false,
ssh_disable_agent_forwarding=true, and passing '-a' to the ssh proxy

Add EC2 filter defintions for future support

EC2 templates have different requirements for the image base definition
that uses filters. As we can have unused variables defined in our vars
files we can just add these extra parameters without causing problems
with OpenStack builds and still support EC2 builds.

The templates are no longer examples but actually fully usable
templates so let us stop calling them examples.

Update templates to using local-*.yaml

This change should allow us to keep the template files relatively
the same while allowing consumers of builder and docker to have
some local modifications in their own ciman repos.

Revert "Bootstrap Ansible if not available"

This is not actually necessary. We need Ansible in the VM that's
running the test not the VM being built. Which means the VM attached
in to Jenkins needs to have Ansible installed in the first place. We
just need to ensure that Jenkins is initially configured with one
(which we currently have to do anyway even for the regular shell
script provisioner).

This reverts commit 99f875674576f3643c9713750a7017f581ff758b.

Initial baseline image (Ansible)

Create a baseline image using Ansible Playbooks. Considering using
Ansible for our Job builds so why not also use it here for packer
builds.

Ansible seems to have support for the things our helper scripts do
which allows us to get rid of them if we use Ansible. Each Ansible
task also validates itself to make sure the commands run through,
something we don't currently do and can better let us know when
something goes wrong.
