Add markdown CI (#5380)

# Node Layouts
Add synthetic scale deployment mode New deploy modes: scale, ha-scale, separate-scale Creates 200 fake hosts for deployment with fake hostvars. Useful for testing certificate generation and propagation to other master nodes. Updated test cases descriptions.

Fix etcd client generation (#10769) * ci: redefine multinode to node-etcd-client This should allow to catch several class of problem rather than just one -> from network plugin such as calico or cilium talking directly to the etcd. * Dynamically define etcd host range This has two benefits: - We don't play the etcd role twice for no reason - We have access to the whole cluster (if needed) to use things like group_by.

There are six node layout types: `default`, `separate`, `ha`, `scale`, `all-in-one`, and `node-etcd-client`.

`default` is a non-HA two nodes setup with one separate `kube_node`
Replace kube-master with kube_control_plane (#7256) This replaces kube-master with kube_control_plane because of [1]: The Kubernetes project is moving away from wording that is considered offensive. A new working group WG Naming was created to track this work, and the word "master" was declared as offensive. A proposal was formalized for replacing the word "master" with "control plane". This means it should be removed from source code, documentation, and user-facing configuration from Kubernetes and its sub-projects. NOTE: The reason why this changes it to kube_control_plane not kube-control-plane is for valid group names on ansible.

`separate` layout is when there is only node of each type, which includes

in the Ansible inventory. This helps test TLS certificate generation at scale
to prevent regressions and profile certain long-running tasks. These nodes are
never actually deployed, but certificates are generated for them.
Improve CI test matrix For Travis CI and GCE, add a naive generator script into a markdown table. Add GCE/Travis CI matrix docs. Add CoreOS test cases. Rework existing cases w/o loosing of coverage. Rework postinstall tests to support CoreOS as well. Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com>

CI: Document the 'all-in-one' layout + small refactoring (#10725) * Rename aio to all-in-one and document it ADTM. Acronyms don't tell much. * Refactor vm_count in tests provisioning

`node-etcd-client` layout consists of a 4 nodes cluster, all of them in `kube_node`, first 3 in `etcd` and only one `kube_control_plane`.
This is necessary to tests setups requiring that nodes are etcd clients (use of cilium as `network_plugin` for instance)

All tests are breakdown into 3 "stages" ("Stage" means a build step of the build pipeline) as follows:
- _unit_tests_: Linting, markdown, vagrant & terraform validation etc...
- _part1_: Molecule and AIO tests
- _part2_: Standard tests with different layouts and OS/Runtime/Network
- _part3_: Upgrade jobs, terraform jobs and recover control plane tests
- _special_: Other jobs (manuals)
The steps are ordered as `unit_tests->part1->part2->part3->special`.
