["Tim Armstrong (Code Review)" <ge...@cloudera.org>]

IMPALA-2343: Add lifecycle timeline to plan nodes

Track the time when Open() and GetNext() are first and last called,
to make it easier to piece together the timeline for fragment execution.

This uses the existing EventSequence infrastructure so that time will
correspond to the fragment instance lifecycle timelines.

These times are not set inside subplans because it would be mostly
redundant with the counters in the containing subplan node.

Testing:
Added a basic test to verify that the event sequence is present.

Perf:
Ran TPC-H 10 locally. There was no significant perf change.

Ran TPC-H Nested locally. There was no significant perf change.
