Tiidy up and refactoring of tasks (#80)
* Tidy up and refactoring of tasks

  - `k3s_config_dir` derived from `k3s_config_file`, reused throughout the role
    to allow for easy removal of "Rancher" references #73.
  - `k3s_token_location` has moved to be in `k3s_config_dir`.
  - Tasks for creating directories now looped to caputure configuration from
    `k3s_server` and `k3s_agent` and ensure directories exist before k3s
    starts, see #75.
  - Server token collected directly from token file, not symlinked file
    (node-token).
  - `k3s_runtime_config` defined in `vars/` for validation and overwritten in
    tasks for control plane and workers.
  - Removed unused references to GitHub API.

* set_fact now uses FQCN

* re-pin molecule<3.2

* Command module now uses FQCN

* Added package checks for #72

* Reorder task files

  - Docker tasks moved into a separate directory for ease of removal #67
  - Bugfix: Control plane on alternate port didn't work.
  - Validation tasks grouped

* Fix Fedora tests

* Add optional documentation links to validations steps #76

* Removed jmespath requirement

* Fix issue with data collection

* Release candidate
