For a deployment behind a firewall/proxy server some additional
environment settings should be passed along, for containers
such as magnum

This commit adds three new properties;
 container_http_proxy
 container_https_proxy
 container_no_proxy

In particular, the user will want to set container_http_proxy
and container_https_proxy properties with the proxy server
details.

In the quickstart guide, the min version of docker is 1.10.0,
and the max version is none. But the `docker daemon` doesn't work
since v1.13.0. Please refer to:
https://docs.docker.com/engine/deprecated/#docker-daemon-subcommand
"docker daemon subcommand
Deprecated In Release: v1.13.0
Target For Removal In Release: v17.12
The daemon is moved to a separate binary (dockerd), and should
be used instead."
I think it's better to let the readers know it.

This change adds enable_fluentd option and enables some other log shippers
to be integrated. When enable_fluentd is "no", syslog server is also disabled.
Then, this change also adds syslog parameters to use a syslog server
prepared by users.

When deploying on arm64, common reports error:
stat /usr/bin/ansible: no such file or directory

The reason is ansible is installed to /usr/local/bin/ansible
rather that /usr/bin/ansible
Fix the issue to call ansible directly, to consider both cases.
