* Ansible: move to Ansible 3.4.0 which uses ansible-base 2.10.10 * Docs: add a note about ansible upgrade post 2.9.x * CI: ensure ansible is removed before ansible 3.x is installed to avoid pip failures * Ansible: use newer ansible-lint * Fix ansible-lint 5.0.11 found issues * syntax issues * risky-file-permissions * var-naming * role-name * molecule tests * Mitogen: use 0.3.0rc1 which adds support for ansible 2.10+ * Pin ansible-base to 2.10.11 to get package fix on RHEL8
