Approach

What is the motivation for this PR?

We encountered a couple new problems after switching to the new style of running everflow tests.

How did you do it?

1. Added a new loganalyzer statement to ignore the NTP time error that pops up because we reset everything.
2. Gave the tests a little longer to collect all the packets because we noticed slower servers were still struggling to keep up with PTF.

How did you verify/test it?

Re-ran the tests locally.

Any platform specific information?

Supported testbed topology if it's a new test case?
