Change logging implementation to Log4j 2. #1531

Closed 1u0 closed 1 year ago

1u0 commented 1 year ago

Description

This changes logging backend from log4j (1.x) to log4j2:

most of sub-projects are changed to use org.slf4j:slf4j-api only, instead of specific org.slf4j:slf4j-log4j12
removed log4j.properties for some sub-projects (mainly used in unit tests setup)
for app the configuration and logging setup was re-written to use log4j2.xml and builtin filters from that library.

Deployment Notes

Should there be release info about change of logging backend (and hence configuration)?
