Go over all logging statements in Weld SE / Servlet and align the way we do logging in Weld SE/Servlet with how it is done in Weld Core. That involves creating new logging interfaces and moving the existing logging statements over.

The rules are:

• if a logging message is of severity INFO, WARN or ERROR, move it to the logger interface
• if the same logging message is used in multiple places (e.g. https://github.com/weld/core/blob/master/environments/se/core/src/main/java/org/jboss/weld/environment/se/Weld.java#L221) then move it to the logger interface
• otherwise, leave the logging statement as it is
