https://media.readthedocs.org/pdf/pip/develop/pip.pdf says that 
trusted-host is available since pip 6.0 (2014-12-22).
IOW there will be problems if an older pip is in use.

Most people upgrade pip at the drop of a hat because usually pip would 
continue to "just work".
IOW adding trusted-host *should* be fine, but you will want to test that.

The option can be added on the command line or in pip.conf.
(It should have been possible in requirements.txt but they forgot to 
implement that; this is fixed since Sep 5, but I don't know whether that 
made it into a pip release yet. See 
https://github.com/pypa/pip/issues/2822 and 
https://github.com/pypa/pip/pull/3007 .)
