jackson suppress serializing properties with null values

[Grim-lock]

https://github.com/ContainX/openstack4j/blob/master/core/src/main/java/org/openstack4j/core/transport/ObjectMapperSingleton.java?utf8=%E2%9C%93#L25
Openstack4j does not serialize properties with null values, and this is a base function.

In octavia, PUT method of Pools:
"A JSON object specifying the session persistence for the pool or null for no session persistence"
pls see https://developer.openstack.org/api-ref/load-balancer/v2/#create-pool for more detail

Is there a easy way to config openstack4j to serialize a null value property?

Grrrrr. OpenStack.
Can we we something like @JsonInclude(Include.ALWAYS) | @JsonInclude(JsonSerialize.Inclusion.ALWAYS) on the attribute @Grim-lock?

It works. I push a patch later
