Interest aggregation scenario: broken due to retransmission suppression change

Description
In IntegrationTests, Interest aggregation scenario (#1384) assumes NFD suppresses all similar Interests when a PIT entry is pending.
When strategies start to permit consumer retransmission, similar Interests are forwarded if they are not too frequent.
With exponential backoff suppression algorithm, the default setting would allow retransmission after only 1ms.
Interest aggregation scenario is broken due to this change, and needs to be redesigned.

I'll scratch the design. After that, this issue will be reassigned for implementation.

I suggest this scenario to be fixed by explicitly setting best-route v1 strategy (ndn:/localhost/nfd/strategy/best-route/%FD%01) which does not allow consumer retransmission.
Other possible solutions are:
- Allow passing parameters to strategies, so that the initial interval of consumer retransmission can be controlled from the scenario.
This is significantly more complex than using best-route v1, and duplicates some work of #2000.
- Disable this scenario.
This is clearly not the best solution.

20150727 conference call approves the design in note-4: set strategy to ndn:/localhost/nfd/strategy/best-route/%FD%01.
- Status changed from New to In Progress
- Status changed from In Progress to Code review
- Blocked by Bug #3073: integ broken due to ndn-cxx shared library added
