Add HostDeviceNetwork basic support

This patch adds HostDeviceNetwork CRD support and basic
transformation to NetworkAttachmentDefinition to allow
Multus create secondary network.

SR-IOV Network Device Plugin is deployed using Network Operator
Helm chart with default configuration.

NOTE: temporary added "//nolint:dupl" before code will be
refactored.

Closes: #44
