IMPALA-4299: add buildall.sh option to start test cluster

A previous commit "IMPALA-4259: build Impala without any test
cluster setup" altered some undocumented side-effects of
buildall.sh.

Previously the following commands reconfigured and restarted the test
cluster. It worked because buildall.sh unconditionally regenerated
the test cluster configs.

  ./buildall.sh -notests && ./testdata/bin/run-all.sh
  ./buildall.sh -noclean -notests && ./testdata/bin/run-all.sh

Instead of restoring the old behaviour and continuing to encourage
mixing use of low and high level scripts like testdata/bin/run-all.sh
as part of the "standard" workflow, this commit adds another
high-level option to buildall.sh, -start_minicluster, that
accomplishes the high-level task of restarting a minicluster with
fresh configs. The above commands can be replaced with:

  ./buildall.sh -notests -start_minicluster
  ./buildall.sh -notests -noclean -start_minicluster
