Let dependencies be defined using file URLs

[lburgazzoli]

As today we do allow to specify dependencies that are available through a maven repository but it should be possible to specify a local developer dependency, like:

kamel run integration.java --dependency file:/path/to/my-dep.jar

Under the hood the dependency should be:

• uploaded to a s3 compatible object storage (i.e. https://min.io) following the maven repo layout
• consumed by camel-k as any other dependency using an s3 wagon.

I can take a look at this if it's ok

To alleviate the constraint of a S3 compatible storage, I was thinking of storing the dependency in a configmap (or an image layer..), WDYT ?
