expanded node build integration

[keeganquinn]

cwnmyr (paired with cwnmyr-build) is already capable of generating OpenWrt images based on configuration in the app. However, the current functionality is not intuitive and only supports a limited set of features. The following are things that might be done to improve this situation:

• Improve UI to make configuration more intuitive
• Finish splash page API integration
• Implement job to handle queuing build requests
• Install user-configured SSH authorized keys during build
• Apply device-configured MAC whitelists during build
• Allow TCP port forwarding to be configured on devices and apply during build

At this time, due to lack of resources on my part, I am not able to continue actively working on this aspect of the project on my own. However, I'd be happy to pair up with anyone who would like to help out, and I'd be glad to accept ideas, discussion, or pull requests on the topic.
