improve how we're logging

[rubiii]

currently, you can change HTTPI.log_level to change the log level we are using to log.
if you look at HTTPI.log, it sends the log_level to the Logger.

that's actually what the Logger's severity should be used for. what i did for savon 2.0 (which used the same method before), was to just log with an appropriately low log level like "debug" or "info" and let people change the Logger's severity to specify what they want to see.

I was thinking in something like you did on savon.

By default have a logger to stdout on info severity. Users can change severity on logger instance, like you said.
Logger be an attribute accessor, so users can change to any logger that wants. File, Syslogger ... etc.

Remove log and log_level attributes. Or warn, and say that will be removed on next version.

About what to log, i can only think on these cases:

• Logs all request options using debug severity.
• Use something like Common Log Format to log request information using info severity.
• Logs response (code, headers, body) using debug severity.
