Subject: ceph-perf: install mdutils and run CBT under gh-venv
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=a4355cd733cf5a1516645e5af5bc691331a488cc;p=ceph-build.git

ceph-perf: install mdutils and run CBT under gh-venv

cbt imports mdutils but ceph/cbt master requirements.txt does not
list it. Install mdutils into gh-venv, put the venv on PATH for
run-cbt.sh, and invoke compare.py via python3 so its /usr/bin/python3
shebang is not used. Only skip CBT runs when the archive dir already
has results, and fail the step if the archive is empty after run-cbt.
