Add a 'log.file.age' configuration parameter to force rotation of log files
after they've reached a certain age

Key: KAFKA-235
URL: https://issues.apache.org/jira/browse/KAFKA-235
Project: Kafka
Issue Type: New Feature
Components: core
Affects Versions: 0.7
Reporter: Mathias Herberts
The Kafka client has the ability to start consuming at an offset before or
after a given point in time. The granularity of this offset is the log file as
the Kafka servers do not keep track of arrival time of various messages.
This means that the granularity of offsets relative to time depends on arrival
rate of messages and thus of log file rotation. A topic with lots of messages
will have its log files rotated very often (thus each spans a short time
interval) whereas a topic with very few messages might not see its log files
rotated for hours.
In order to circumvent this granularity disparity, having a parameter that
would force log file rotation after a certain delay (xxx ms) would allow for
pretty much constant time granularity to be available at the cost of more file
descriptor being used.
