Choose ONOS nodes so that only one partition looses a majority

- Fix counter check to only look at the counters used by the test
- Add the gen-partition file to the repo and make the test copy it to
  the right place in ONOS
- clear buffer in clidriver after secureCopy
- Change individual ping timeout for ping functions in mininet driver
- increase links timeout in mininet driver due to occasional failures
- Kill iperf if it timesout to allow continued use of mininet
- Clear buffer at the end of many onos driver functions

+This test is designed to verify that an ONOS cluster behaves correctly when
+ONOS nodes die. Currently, we will kill nodes so that each raft partition will
+lose a member, but we make sure that there is always a majority of nodes
+available in each partition.
+
+As written, the test only supports an ONOS cluster of 3,5, or 7 nodes.
+This is because the test doesn't apply to a single node cluster, ONOS clusters
+should be deployed in odd numbers, and the partition generation and node
+killing scheme used doesn't give the same properties for clusters of more
+than 7 nodes. Namely, each partition won't have exactly one node killed.
+
+The gerneral structure for the test:
+- Startup
+- Assign switches
+- Verify ONOS state and functionality
+    - Device mastership
+    - Intents
+    - Leadership election
+    - Distributed Primitives
+- Kill some ONOS nodes
+- Verify ONOS state and functionality
+- Dataplane failures
+    - link down and up
+    - switch down and up
