ovirt-provider-ovn log

Description of problem:
To add a test which creates 50 networks efficiently on a single provider request, ovirt-provider-ovn should provide the option of bulk create networks, as it is specified in the Neutron API under networks: https://developer.openstack.org/api-ref/network/v2/index.html#bulk-create-networks

Version-Release number of selected component (if applicable):
ovirt-provider-ovn-1.2.5-1.el7ev.noarch
RHV 4.2.1.3-0.1.el7

How reproducible:
100%

Steps to Reproduce:
1. Try to create bulk of networks during network creation (according to  https://developer.openstack.org/api-ref/network/v2/index.html#bulk-create-networks)
POST on /v2.0/networks with body:
{
    "networks": [
        {
            "admin_state_up": true,
            "name": "network_1",
        },
        {
            "admin_state_up": true,
            "name": "network_2",
        }
    ]
}

Actual results:
Provider throws bad request exception:
{
    "error": {
        "message": "'network'",
        "code": 400,
        "title": "Bad Request"
    }
}

Expected results:
Bluk creation should be supported.

Additional info:
Current workaround: for each network - create single network creation request.
