Add new network activators to bring up interfaces (#919)
Currently _bring_up_interfaces() is a no-op for any distro using renderers. We need to be able to support bringing up a single interfaces, a list of interfaces, and all interfaces. This should be independent of the renderers, as the network config is often generated independent of the mechanism used to apply it. Additionally, I included a refactor to remove "_supported_write_network_config". We had a confusing call chain of apply_network_config->_write_network_config->_supported_write_network_config. The last two have been combined.
