[FEATURE REQUEST] Allow adding Shipping partners from config or UI

[dheeth]

Is your feature request related to a problem? Please describe.
I can see that adding a new shipping partner only requires name and tracking url with parameterized value but there is no option to add/override these from config json or Admin panel

Describe the solution you'd like
It should not need any modules to add/override Shipping partners

Hi @dheeth ,

You can add a carrier from the configuration file (json).

{
...,
"oms": {
        "carriers" : {
            "test": {
                    "name": "Test",
                    "trackingUrl": "https://tools.usps.com/go/TrackConfirmAction?qtc_tLabels1={trackingNumber}"
                }
        }
    }
}

Thanks
