fix flakes on e2e test TCP CLOSE_WAIT timeout
fix flakes on e2e test TCP CLOSE_WAIT timeout

it turns out that the e2e test was no using the timeout used to
hold the CLOSE_WAIT status, hence the test was flake depending
on how fast it checked the conntrack table.

This PR replaces the dependency on ssh using a pod to check the conntrack
entries on the host in a loop, to make the test more robust
and reduce the flakiness due to race conditions and/or ssh issues.

It also fixes a bug trying to grep the conntrack entry, where
the error was swallowed if a conntrack entry wasn't found..
