Our common logger is a logging facade just like SLF4J.
We can enhance it to support parametrized logging
We have many places like this:
```
if (logger.isInfoEnabled()) {
logger.info("aaa" + "bbb" + "ccc");
}
```
We are using logging guard to avoid unnecessary string concatenate.
With the support of parametrized logging, this can be simplified just like:
```
logger.debug("Hello world {} {} and {}", a, b, c);
```
Similar feature discribed in SLF4j:

Question: Any other points can be enhanced?
