Add parameter --no-trusted-host: Don't add trusted host to generated file

[mckelvin]

Describe the issue briefly here.

Steps to replicate

1. Prepare ~/.pip/pip.conf

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
extra-index-url = http://devpi.arpanet/private/dev/+simple
trusted-host = devpi.arpanet

[search]
index = http://devpi.arpanet/private/dev/

Then
2. pip-compile --no-index --upgrade --output-file requirements.txt requirements.in

Expected result

--trusted-host devpi.arpanet should not existed in requirements.txt

Actual result

I wish there's a option in pip-sync like --no-index which won't write --trusted-host devpi.arpanet into the generated requirements.txt.

+1 this is kind of awkward. My global .pypirc or pip config or whatever it's reading from has a trusted host that I use for development on a specific project, but the host is being included in every project for which I pip-compile now. There's probably other solutions to this problem, but this seems obvious.
