Subject: macros, docs, releng: Use `sudo -H` pip install
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=2b9009385839d6dc33beabd4eb833b179d4693f4;hp=2b9009385839d6dc33beabd4eb833b179d4693f4;p=releng.git

macros, docs, releng: Use `sudo -H` pip install

This is still far from a clean and secure approach, as `pip install`
should not be ran with `sudo`.
However, `-H` limits the area we touch and also fixes some incompat
between disto-provided pip and pip-provided pip.
