Drop Ansible support for v2.9 and v2.10 (#8925)

Ansible v2.9 and v2.10 are EOL as [1].
This drops those version supports by following the upstream Ansible.

This sets use_ssh_args true always because that is required to use
ssh_args on ansible.cfg on Ansible v2.11 or later[2].

ansible_ssh_host is replaced with ansible_host because ansible_ssh_host
has been deprecated already and cenots7 jobs were failed due to the
deprecated ansible_ssh_host.
