`Iterator.continually` is more efficient (it doesn't allocate a `Cons` instance per element) and we don't need the extra functionality provided by `Stream.continually`.

I originally tried to solve the problem by using tempfile, and creating and using scp() utility method that created a random local temp file every time it was called. However, it required passing miniKdc object to SecurityConfig setup_node which looked very invasive, since many tests use this method. Here is the PR for that, which I think we will close: https://github.com/apache/kafka/pull/609
This change is the least invasive change to solve conflicts between multiple tests jobs.

In `wrapForOutput` and `wrapForInput` methods of `org.apache.kafka.common.record.Compressor`, `Class.forName("[compression codec]")` and `getConstructor` methods are invoked for each `wrapForOutput` / `wrapForInput` call. Reflection calls are expensive and impact performance at high volumes. This patch adds a cache for `Constructor` to reduce the reflection overhead.
In our production deployments, this has reduced producer CPU usage by about 20%
