David Knupp 6e5ec22b12 IMPALA-7399: Emit a junit xml report when trapping errors
This patch will cause a junitxml file to be emitted in the case of
errors in build scripts. Instead of simply echoing a message to the
console, we set up a trap function that also writes out to a
junit xml report that can be consumed by jenkins.impala.io.

Main things to pay attention to:

- New file that gets sourced by all bash scripts when trapping
  within bash scripts:

  https://gerrit.cloudera.org/c/11257/1/bin/report_build_error.sh

- Installation of the python lib into impala-python venv for use
  from within python files:

  https://gerrit.cloudera.org/c/11257/1/bin/impala-python-common.sh

- Change to the generate_junitxml.py file itself, for ease of
  https://gerrit.cloudera.org/c/11257/1/lib/python/impala_py_lib/jenkins/generate_junitxml.py

Most of the other changes are to source the new report_build_error.sh
script to set up the trap function.
