+1 to drop Java 7 support

Hi users!
Flink currently maintains backwards compatibility for savepoint
formats, which means that savepoints taken with Flink version 1.1.x
and 1.2.x can be resumed in Flink 1.3.x
We are discussing how many versions back to support. The proposition
is the following:
* Suggestion: Flink 1.4.0 will be able to resume savepoints taken
with version 1.3.x and 1.2.x, but not savepoints from version 1.1.x
and 1.0.x*
The reason for that is that there is a lot of code mapping between the
completely different legacy format (1.1.x, not re-scalable) and the
key-group-oriented format (1.2.x onwards, re-scalable). It would
greatly help the development of state and checkpointing features to
drop that old code.
Please let us know if you have concerns about that.
Best,
Stephan
