NIFI-9576: Introduced a BlockListClassLoader that can be used by stateless in
order to isolate both the Stateless Engine and the NiFi extensions from
extraneous classes that exist in the System ClassLoader
This closes #5705.

> ClassLoader isolation for Stateless NiFi
> ----------------------------------------
>
> Key: NIFI-9576
> URL: https://issues.apache.org/jira/browse/NIFI-9576
> Project: Apache NiFi
> Issue Type: Improvement
> Components: NiFi Stateless
> Reporter: Peter Turcsanyi
> Assignee: Peter Turcsanyi
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> When Stateless NiFi is running embedded within an application (like Kafka
> Connect), then the hosting app has its own class loader mechanism and system
> class path that may conflict with NiFi's class loading / class path. E.g.
> Kafka's {{libs}} folder (v2.8.x) contains {{jackson}} dependencies that are
> incompatible with NiFi (v1.15.x).
> Implement a class loading mechanism that is able to isolate NiFi's class
> loaders from the embedding environment.
