For every test number N run in process with PID, we take address
127.N.PID/256.PID%256 and let Gerrit listen on its default ports (29418
for SSH and 8080 for HTTP) on that address. We also name site dir with
the same address with "site-" prefix.
Thanks to Clark Boylan for this great idea.

Provide intergation testing for the git-review utility. Requires
Gerrit war file (like 2.6.1-gerrit.war) in the .gerrit directory in
the git-review project (like git-review/.gerrit/2.6.1-gerrit.war).
Tests start local Gerrit and create test user and project there to
be used.
