Change docker_container parameter network to network_mode

Addressing "populate kv_store with custom ceph.conf":
Unsupported parameters for (docker_container) module. Looking at
https://docs.ansible.com/ansible/latest/modules/docker_container_module.html
shows that the correct parameter is network_mode, not network.
