Bob Lantz f6de358b06 Try to prime the pump to avoid PACKET_INs during iperf test 
Background: the reference controller is reactive and installs exact
match rules. By attempting to start a telnet session we make sure that
the ARP caches and TCP flow rules are set up (in one direction at
least) before the test starts.

This is intended to help with #413

Bob Lantz 098bede0ec Wait for controller shutdown. 
Unfortunately, this can slow things down a bit - perhaps
100-200 ms in the case of ovs-controller, but I am hoping that
it may help slightly with #399.

Bob Lantz 1bae1aab03 Turn of ntpd and set date manually before tests 
This should fix the problem where we see the first test
taking negative time, as well as possibly other issues
with performance tests which may be sensitive to changes
in wall clock time.

Bob Lantz ec26c7492d Install vconfig in VM for VLAN example

the root issue of the example failing silently when
vconfig is missing.
