SAMZA-2418: Integration tests are failing and do not properly pass params to zopkio

[cameronlee314]

Symptom: ./bin/integration-tests.sh /tmp/samza-tests yarn-integration-tests --nopassword fails and does not respect the --nopassword parameter. Some of the documentation for testing does not have the correct commands for executing tests (i.e. missing yarn-integration-tests or standalone-integration-tests argument)

Cause:

1. The slf4j binding was removed by SAMZA-2155: Remove log4j log4j2 dependency from samza-test #985, but the integration test depends on some of those stdout logs.
2. An additional yarn-integration-tests or standalone-integration-tests argument was added by SAMZA-1748: Standalone failure tests. #554, but it looks like the argument parsing was not correctly updated to find the zopkio parameters. Also, not all of the test documentation was updated in that change.

Fix:

1. Add log4j2 dependency and log4j2.xml back in to the samza-test module so the integration test package which pick it up and send logs to stdout.
2. Fixed the argument parsing to use the correct argument slice. I also changed "${*:3}" to "${@:3}" since @ seems to be the cleaner in general (https://unix.stackexchange.com/questions/41571/what-is-the-difference-between-and); although I think * still worked in this case.

Tests:

1. Verified that ./bin/integration-tests.sh /tmp/samza-tests yarn-integration-tests --nopassword and ./bin/integration-tests.sh standalone-integration-tests --nopassword both succeed and do not ask for a password.
2. ./bin/integration-tests.sh /tmp/samza-tests yarn-integration-tests got to the stage where zopkio asked for a password.
