Review request for Flume and Prasad Mujumdar.
Summary
-------
Added support for specifying the capacity of the JDBC channel. If a non-zero
positive value is specified, the channel enforces it as the limit on total
number of events persisted at any time. If a zero/negative/unspecified value is
provided, the channel operates without any limit. Added a test case as well to
exercise this functionality.
Another change that I am sliding in is reducing the overall number of events
that tests exercise - from about 2000 to close to 200. This will greatly reduce
the amount of time the tests take when running on the JDBC channel module. The
test functionality remains the same.
This addresses bug FLUME-820.

> users should be able to specify capacity for the JDBC channel in terms of
> total number of events stored. This will help ensure that the channel does
> not overwhelm the system by occupying the entire available disk space.
