Remove log4j1 from bk test code

Remove log4j1 from bk test code

### Motivation
this is a part work of remove log4j1 from bookeeper, first remove it from our test code, unit test and integrate test

### Changes
- remove log4j1 scope test dependency
- use log4j2.xml instread of log4j.properties
- introduce testtools module to reduce duplication,  if a module needs particular configuration (very unlikely) we can add a log4j2-test.xml file which has precedence over log4j2.xml one. idea from [nicoloboschi](https://github.com/nicoloboschi)
