Title: Fix log format for http server and http channel objects

I set log level to `blather` and then I access to http server `http://127.0.0.1:9001/`.
Next, I check the log file /tmp/supervisord.log and it has the following lines:
(omitted date and time)
```
BLAT read event caused by
BLAT read event caused by
BLAT read event caused by
BLAT write event caused by
```
I think that the above lines don't make sense because they did not show object's module name and class name. They should show as follows:
```
BLAT read event caused by
BLAT read event caused by
BLAT read event caused by
BLAT read event caused by
```
