CLI - Make kamel run handle github urls that are not raw

[davsclaus]

For example if you browse code on github you may see this example

https://github.com/apache/camel-k/blob/master/examples/hello.xml

And then want to run it via

kamel run https://github.com/apache/camel-k/blob/master/examples/hello.xml

But it requires the raw url

kamel run https://raw.githubusercontent.com/apache/camel-k/master/examples/hello.xml

We could maybe make the kamel run command detect the github url and automatic transform the url to the raw url so it can download the source correctly (eg github.com /blob/ -> raw style)
