Add ability to upload the project config via HTTP

[stuartc]

Configuration via containers in a non-local (k8s, remote docker) environment is very difficult as there is no local volume mount (at least not without significant effort).

How about the ability for the app to boot without config, and have uploaded via http - storing it locally (or in a pvc/volume) for subsequent startups.

Something like this? Would it take a .yaml? Or a .json project spec?

[stuartc]

Yes first it would take a .yaml file... whatever that mime type is... after that we can add json (should be a 1:1 representation of the yaml)...

Then we can chat down the line about more detailed/specific interfaces, like chaging one job etc..

@chaiwa-berian , I've sketched out a possible approach on the reconfig branch. Want to take a peek?
