[ZEPPELIN-2162] [ZEPPELIN-2142] Make travis_check.py work with fork under organization, and show guidance if travis is not configured

### What is this PR for?

When contributor uses zeppelin fork under organization, Jenkins can't check it with current travis_check.py.

This PR updates travis_check.py to distinguish error 1 when it fails with build fail, error 2 when it can't find build.

When it fails with 2, jenkins configuration can retry travis_check.py with organization repo.

Even though it tried again, still get 2 in return, then print instruction how to configure travis-ci.

Jenkins configuration is updated

from
```bash
if [ -f "travis_check.py" ]; then
  git log -n 1
  STATUS=$(curl -s $BUILD_URL | grep -e "GitHub pull request.*from.*" | sed 's/.*GitHub pull request <a href=\"\(https[^"]*\).*from[^"]*.\(https[^"]*\).*/\1 \2/g')
  AUTHOR=$(echo $STATUS | sed 's/.*[/]\(.*\)$/\1/g')

  fi
  sleep 30 # sleep few moment to wait travis starts the build
  python ./travis_check.py ${AUTHOR} ${COMMIT}
else
  echo "travis_check.py does not exists"
  echo "assume it's gh-pages branch"
  echo "return okay"
