Description

The idea is to be able to configure easily the LOG LEVEL of package: 
org.apache.unomi.schema.impl
 
In case people experience trouble with schema validation, it would be require to switch this log to DEBUG to have real informations.
 
the file to modify is: https://github.com/apache/unomi/blob/master/package/src/main/resources/etc/org.ops4j.pax.logging.cfg
 
Like for cxf example in same file:

log4j2.logger.cxfInterceptor.name = org.apache.cxf.interceptor
log4j2.logger.cxfInterceptor.level = ${org.apache.unomi.logs.cxf.level:-WARN} 

associated to env (custom.system.properties): 

org.apache.unomi.logs.cxf.level=${env:UNOMI_LOGS_CXF_LEVEL:-WARN} 

 
Do something like this:

log4j2.logger.jsonSchema.name = org.apache.unomi.schema.impl 
log4j2.logger.jsonSchema.level = ${org.apache.unomi.logs.jsonschema.level:-INFO} 

to be associated env variable (custom.system.properties): 

org.apache.unomi.logs.jsonschema.level=${env:UNOMI_LOGS_JSONSCHEMA_LEVEL:-INFO}
