Investigate whether Boost.log could replace log4cplus
Kea has few core dependencies - boost, log4cplus and one of either OpenSSL or Botan. The log4cplus has been in use since the very beginning and was inherited from BIND10 days a decade ago. We never seriously looked at alternatives.
Dependency on log4cplus is sometimes a problem, especially in newer systems. Here's an example of problems on CentOS8.
The goal of this ticket is to:
- investigate if boost.log can possibly be used as a replacement
- provide an estimate of how much work would it take to do it
This ticket is not about doing the migration itself.
