Review Ansible-Lint skipped rules

[kpouget]

In this PR we updated the Ansible linter, but also introduce multiple "skipped" rules (to keep the CI green).

These skipped rules should be reviewed, and decided one by one if the rule should be enforced or skipped.

Rules that are skipped:

  - 'command-instead-of-module'
  - 'command-instead-of-shell'
  - 'deprecated-local-action'
  - 'key-order[task]'
  - 'jinja[spacing]'
  - 'no-free-form'
  - 'chema[meta]'
  - 'name[missing]'
  - 'var-naming[no-reserved]'
  - 'var-naming[no-role-prefix]'
  - 'var-naming[pattern]'
  - 'yaml[colons]'
  - 'yaml[commas]'
  - 'yaml[comments]'
  - 'yaml[empty-lines]'
  - 'yaml[indentation]'
  - 'yaml[key-duplicates]'
  - 'yaml[line-length]'
  - 'yaml[new-line-at-end-of-file]'
  - 'yaml[octal-values]'
  - 'yaml[trailing-spaces]'
  - 'yaml[truthy]'
  - 'name[template]'
  - 'name[casing]'
  - 'risky-file-permissions'
  - 'risky-shell-pipe'
  - 'ignore-errors'
  - 'no-changed-when'
  - 'fqcn'
  - 'args[module]'

rules that should be enforced, at first glance:

-    command-instead-of-shell
-    jinja[spacing]
-    yaml[new-line-at-end-of-file]
-    risky-shell-pip
-    name[missing]
