Change from ```logging``` to ```logger``` because we wish to see the
information about the module where the logging message came from so that
it's easier to diagnosing problems. I changed ```logging``` to
```logger``` in modules ```reviews```, ```webapi``` and ```ssh```.

Testing Done:
Test using the tests in the ```reviews```, ```webapi``` and ```ssh```
modules' repositories. Using the following commands:

./tests/ reviewboard.webapi.tests
./tests/ reviewboard.ssh.tests
All three test sets are passed.
