operations guide about setting local repo misleads

[Evgeny Kozhemyakin]

Our operations guide is misleading in the part of setting up local repository.

===
The script supports running behind an HTTP proxy as long as the proxy is configured to allow proxying to Port 873 (rsync). The following environment variables can be set either system-wide (via ~/.bashrc), or in the script configuration file (see below):

http_proxy=http://username:password@host:port/
RSYNC_PROXY=username:password@host:port
===

fuel-createmirror is a shell wrapper for fuel-mirror which works only wih http (or https), not rsync.
As well setting "http_proxy" prevents fuel-mirror's connection to keystone on master in most cases.
The workaround could be
 export http_proxy=http://<proxy>
 export no_proxy=10.20.0.2
