Run from GitHub

It is possible to run integrations from GitHub with a dedicated URL syntax:

kamel run github:$user/$repo/$path?branch=$branch

As example, running the following command

kamel run github:apache/camel-k/examples/

is equivalent to:

kamel run

but does not require to type the full GitHub RAW URL.

Declaring the branch query param is not required and defaults to master if not explicit set.
