ansible: add httplib2

[richardlau]

V8's gclient.py now requires httplib2. Install it on all the
machines that the V8 CI can run on.

Fixes: #2880

This proved to be very tricky on the RHEL 7 s390x (LinuxONE) instances. httplib2 refused to install via pip2 with the following error:

$ sudo pip2 install httplib2
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

I even tried sudo pip2 install glob2 (which some searches suggested to install for glob) but still got the above error. In the end I had to disable PEP 517 (--no-use-pep517) but I had to pick an older version of httplib2 because the later ones require PEP 517.

And to cap everything off the adoptopenjdk tasks were failing due to a mismatched checksum on the downloaded binary compared to the metadata from the AdoptOpenJDK REST API. I've switched the RHEL7 s390x instances back to the java-1.8.0-openjdk yum package. I also registered the RHEL 7 instances with our RHEL subscription so that we get the most up to date packages.

Maybe the tools are now able to run with Python 3?

We'd still need to be able to run the job against older Node.js release lines.
