The openstackclient is the preferred CLI for OpenStack
environments and should be used instead of novaclient.

* Add support for Packet with Terraform

Co-Author: johnstudarus <john@jhlconsulting.com>

* removed advanced features to streamline

* clarifying usage

* Update README.md

provide a better test to validate things are working OK

* Update README.md

clarifying what to set

* minor wordsmithing

* Fix admin cert path

* clarifying how to configure keys

* enabling kubeconfig_localhost

pull over the configuration file via playbooks rather than the key files individually

* Create output.tf

* Add support for node specific plans

* [contrib/terraform/openstack] Add worker_allowed_ports

  Allow user to define in terraform template which ports and remote
  IPs that are allowed to access worker nodes. This is useful when you
  don't want to open up whole NodePort range to the outside world, or
  ports outside NodePort range.

fix typos in line 114 and 116: doesnt -> doesn't

* Add an 'access_ip' for openstack resources to the terraform inventory builder script

* Update Openstack README

* Only use ipv4

* If there's a floating IP assigned to an openstack instance, use that for access_ip

Update template to have bastion section

* Automatically infer bootstrap_os

* Rename bootstrap os to os_family

* Replace `openstack_compute_secgroup_v2` with `openstack_networking_secgroup_v2`

The `openstack_networking_secgroup_v2` resource allow specifications of
both ingress and egress. Nova security groups define ingress rules only.

This change will also allow for more user-friendly specified security
rules, as the different security group resources have different HCL
syntax.

allow masters, nodes and gluster nodes (within each group) to be scheduled
on differents AZ.

Attempting to clarify the language surrounding the etcd node deployment script failure mechanism. I had this error when doing a new cluster deployment last night and, though it should have been, it wasn't immediately apparent to me what was causing the issue (since my default master node hostnames do not specify whether they are also acting as etcd replicas).

This will make NodePort services work out of the box

Add TF_VAR_ to terraform env

* Add supplementary node groups

  To add additional ansible groups to the k8s nodes, such as
  `kube-ingress` for running ingress controller pods. Empty by default.

* [terraform/openstack] Restores ability to use existing public nodes and masters as bastion.

* [terraform/openstack] Uses network_id as output

* [terraform/openstack] Fixes link to inventory/local/group_vars

* [terraform/openstack] Adds supplementary master groups

* [terraform/openstack] Updates documentation avoiding manual setups for bastion (as they are not needed now).

* [terraform/openstack] Supplementary master groups in docs.

* [terraform/openstack] Fixes repeated usage of master fips instead of bastion fips

* [terraform/openstack] Missing change for network_id to subnet_id

* [terraform/openstack] Changes conditional to element( concat ) form to avoid type issues with empty lists.
