Description

While testing Sentry 2.0, I found that the logging was not working correctly due to some log4j2 dependencies that were added on the classpath by Hive 2 dependency.

Sentry has a mix of log4j and SLF4J api usage, so having these mix of dependencies have conflict with the Sentry logging. We should exclude these log4j2 dependencies for the Sentry 2.0 release.

The libraries that were added and should be excluded are:
log4j-1.2-api-2.6.2.jar
log4j-api-2.6.2.jar
log4j-core-2.6.2.jar
log4j-slf4j-impl-2.6.2.jar
log4j-web-2.6.2.jar

The only library that should exist on the classpath is:
log4j-1.2.16.jar
