feat(controller): skip appending VM LSPs if default Multus network is present (#5106)

Updated the logic in getVMLsps to check for a default Multus network in VM specifications. If a default Multus network is found, the corresponding VM LSP will not be appended to the list. This change ensures that only VMs without a default Multus network are processed for LSP creation.
