* Remove Vault

* Remove reference to 'kargo' in the doc

* change check order

This is rather convenient if you want to configure exceptions on a
company firewall.

This give users the option to define multiple ssh public keys when
deploying the base infrastructure on Azure.

* [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

appropiate->appropriate

* 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

* failed

* version_compare

* succeeded

* skipped

* success

* version_compare becomes version since ansible 2.5

* ansible minimal version updated in doc and spec

* last version_compare

* [jjo] add DIND support to contrib/

- add contrib/dind with ansible playbook to
  create "node" containers, and setup them to mimic
  host nodes as much as possible (using Ubuntu images),
  see contrib/dind/README.md

- nodes' /etc/hosts editing via `blockinfile` and
  `lineinfile` need `unsafe_writes: yes` because /etc/hosts
  are mounted by docker, and thus can't be handled atomically
  (modify copy + rename)

* dind-host role: set node container hostname on creation

* add "Resulting deployment" section with some CLI outputs

* typo

* selectable node_distro: debian, ubuntu

* some fixes for node_distro: ubuntu

* cpu optimization: add early `pkill -STOP agetty`

* typo

* add centos dind support ;)

* add kubespray-dind.yaml, support fedora

- add kubespray-dind.yaml (former custom.yaml at README.md)
- rework README.md as per above
- use some YAML power to share distros' commonality
- add fedora support

* create unique /etc/machine-id and other updates

- create unique /etc/machine-id in each docker node,
  used as seed for e.g. weave mac addresses

- with above, now netchecker 100% passes WoHooOO!
  🎉 🎉 🎉

- updated README.md output from (1.12.1, verified
  netcheck)

* minor typos

* fix centos node creation, needs earlier udevadm removal to avoid flaky facts, also verified netcheck Ok \o/

* add Q&D test-distros.sh, back to manual /etc/machine-id hack

* run-test-distros.sh cosmetics and minor fixes

* run-test-distros.sh: $rc fix and minor formatting changes

* run-test-distros.sh output cosmetics

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.

* add metallb as loadbalancer for on premise deployments

* improve configuration

* add variables to DaemonSet

Remove duplicate hostname usage.
