Below build failure was reported on some Jenkins perf jobs.

Traceback (most recent call last):
  File "src/mongo/base/generate_error_codes.py", line 45, in <module>
    from Cheetah.Template import Template
ImportError: No module named Cheetah.Template

+ exit 2
Build step 'Execute shell' marked build as failure

Mathias Stearn mentioned in his email "eeny meeny miny mo, catch an error by its code ... or category" that some recent DBException enhancement commits could have caused python import error and broke the build. Need to upgrade the python cheetah module to get it fixed, specifically, run "python -m pip install -r buildscripts/requirements.txt" in the relevant Jenkins build directories.

Following WT Jenkins hosts need the fix:

aws-perf
kodkod
margay
ocelot
windows-performance
