[Request]: Support loading network configuration from file

[katiewasnothere]

Feature or enhancement request details

Today our network plugin will take in a set of parameters for configuring the network we're trying to make. Instead, we could load the network configuration from a fixed path in the container bundle. This would allow us to be more flexible in what options we send to different network plugins.
