Switch http.java.sampler.retries to 1

[Philippe Mouawad]

Hello,
To align HttpClient with Java behaviour, I suggest that as for HttpClient,
we switch this property to 0.


Property is by the way not greatly named as a value of 1 means 0 retry.

So maybe we should also fix the algorithm so that 0 means no retry.

int retry = -1;
for (; retry < MAX_CONN_RETRIES; retry++) {
