the rational for this is to allow admin console to change a the flavor

param partner to 0. This is for things like say, a plugin to allow users
to add flavors via admin console which is actually being developed right
now by Panda.

The reason why this is needed is because you cannot impersonate partner
0, see api_v3/lib/KalturaDispatcher.php
// prevent impersonate to partner zero
$p = isset($params["p"]) &&
$params["p"] ? $params["p"] : null;
