Confluent's Python client for Apache Kafka

v1.4.2 is a maintenance release with the following fixes and enhancements:

• Fix produce/consume hang after partition goes away and comes back,
  such as when a topic is deleted and re-created (regression in v1.3.0).
• Consumer: Reset the stored offset when partitions are un-assign()ed.
  This fixes the case where a manual offset-less commit() or the auto-committer
  would commit a stored offset from a previous assignment before
  a new message was consumed by the application
• Seed random number generator used for random broker selection.
• Multiple calls to Consumer.close will not raise RunTimeError (@mkmoisen , #678)
• Module lookup failures raise ImportError (@overstre #786)
• Fix SchemaRegistryClient basic auth configuration (@blown302 #853)
• Don't send empty credentials to SR in Authorization Header (#863)
• miscellaneous test cleanup and enhancements (@nicht #843 ,#863)
