Added logback-classic exclusion for nifi-properties-loader used by
nifi-toolkit-encrypt-config
Updated log4j.properties logging pattern and logger config in
nifi-toolkit-assembly and nifi-toolkit-zookeeper-migrator, filtering zookeeper
messages below WARN

> Project: Apache NiFi
> Issue Type: Bug
> Components: Tools and Build
> Affects Versions: 1.1.0
> Reporter: Jeff Storck
> Assignee: Jeff Storck
> Fix For: 1.1.0
>
>
> The ZooKeeper Migrator Toolkit has a dependency on ZooKeeper 3.4.6 which has
> a hard dependecy on log4j, which conflicts with nifi-property-loader's
> dependency on logback. When the toolkit runs, SLF4J finds two logging
> implementations to bind to and complains, and according to SLF4J's
> documentation, it is considered random which implementation SLF4J will use.
> The command line output should be modified to adhere to the standard
> established by the other tools in the toolkit.
