``DvrDriver`` and ``OvnDriver`` incorrectly define distributed flag

[Rodolfo Alonso]

The class ``L3ServiceProvider`` defines the distributed support with the class variable "distributed_support" [1]. The classes ``DvrDriver`` and ``OvnDriver`` are using the variable "dvr_support" instead.

The method to ensure a driver "ha" and "distributed" support uses "distributed_support" too [2].

    ``OvnDriver`` and ``DvrHaDriver`` to use "distributed_support" variable

    ``OvnDriver`` and ``DvrHaDriver`` classes were using an incorrect
    variable name to define the DVR support, that should be
    "distributed_support" instead of "dvr_support".
