* Use a fixed `Random` seed in `EndToEndLatency.scala` for determinism
* Add `compression_type` to and remove `consumer_fetch_max_wait` from `end_to_end_latency.py`. The latter was never used.
* Tweak logging of `end_to_end_latency.py` to be similar to `consumer_performance.py`.
* Add `compression_type` to `benchmark_test.py` methods and add `snappy` to `matrix` annotation
* Use randomly generated bytes from a restricted range for `ProducerPerformance` payload. This is a simple fix for now. It can be improved in the PR for KAFKA-3554.

* The hope is that RocksDb 4.4.1 is more stable than 4.1.0 (occasional segfaults) and 4.2.0 (very frequent segfaults), release notes for 4.4.1: https://www.facebook.com/groups/rocksdb.dev/permalink/925995520832296/
* slf4j 1.7.21 includes thread-safety fixes: http://www.slf4j.org/news.html
* snappy 1.1.2.4 includes performance improvements requested by Spark, which apply to our usage: https://github.com/xerial/snappy-java/blob/master/Milestone.md
I ran the stream tests several times and they passed every time while 4.2.0 segfaulted every time.

This should make Log.read act the same when startOffset is larger than maxOffset as it would if startOffset was larger than logEndOffset. The current behavior can result in an IllegalArgumentException from LogSegment if a consumer attempts to fetch an offset above the high watermark which is present in the leader's log. It seems more correct if Log.read presents the view of the log to consumers as if it simply ended at maxOffset (high watermark).
I've tried to describe an example scenario of this happening here https://issues.apache.org/jira/browse/KAFKA-725?focusedCommentId=15221673&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15221673
I'm not sure I understand why ReplicaManager sets maxOffset to the high watermark, and not high watermark + 1. Isn't the high watermark the last committed message, and readable by consumers?
Tests passed for me locally on second try, seems like it just hit a flaky test.

This PR: https://github.com/apache/kafka/pull/958 fixed the use of prop_file in the situation when we have multiple producers (before, every producer will add to the config). However, it assumes that self.prop_file is initially "". This is correct for all existing tests, but it precludes us from extending verifiable producer and adding more properties to the producer config (same as console consumer).
This is a small PR to change the behavior to the original, but also make verifiable producer use prop_file method to be consistent with console consumer.
Also few more fixes to verifiable producer came up during the review:
-- fixed each_produced_at_least() method
-- more straightforward use of compression types
granders please review.
