Content-Type header removed for POST with empty (0 length) payload starting in v3.10.2

[Blackbaud-ChrisBlythe]

Starting in v3.10.2, we have found that Gatling is removing our explicitly defined Content-Type headers on POST requests that have an empty (0 length) payload.

We have confirmed that v3.10.1 (and all previous versions we've used over the years) preserves the Content-Type header in this situation, while v3.10.2 and v3.10.3 both remove the header.

Already fixed in #4509
Waiting for a new release to ship
