This is merged from three cherry-picked patches, all needed in order to
pass gate testing. Make neutron-grenade non-voting in gate because
dropping it there would be complicated.
Use packaged uwsgi on Fedora and Ubuntu
Building uwsgi from source was a workaround that was introduced a long
time ago, it doesn't seem like it is needed anymore and will actually
fail for Ubuntu 20.04.
Also it doesn't match what will happen for most real-world
installations, so let's try to get back to using distro packages. We'll
still use the source install for RHEL/Centos, it remains to be tested
whether we can get back to using distro versions there, too.
Use uwsgi binary from path
All these uwsgi invocations assume that the uwsgi binary is in the
same directory as their project binaries are installed into (probably
/usr/bin). That may not be correct -- for example if using a packaged
uwsgi on Fedora the binary will live in /usr/sbin/uwsgi (not /usr/bin
where the project files from pip are).
Switch invocations to just find it in the path.
