mimic: build/ops: admin/build-doc: use python3 #30663
to address sphinx-doc/sphinx#3620, we need to use sphinx with its fix at sphinx-doc/sphinx@e049f86 in other words, we need to use sphinx v2.0.0 and up. but sphinx 2.0 requires python >= 3.5, so we have to use python3 for building the documents. in this change: * doc-requirements.txt: install python3 packages on debian derivatives * build-doc: install python3.6 packages from EPEL7, and use python3 venv for using sphinx2 * doc-requirements.txt: bump up all python packages to latest stable. Signed-off-by: Kefu Chai <firstname.lastname@example.org> (cherry picked from commit ace8cb1) Conflicts: admin/doc-requirements.txt
