Add modeline support for Camel K runtime config (e.g. secrets, configmap)

[christophd]

Users are able to add modeline instructions to add runtime configuration such as secrets or configmaps.

Example modeline:

// camel-k: config=secret:my-secret
// camel-k: config=configmap:my-settings

YAKS should support this kind of runtime configuration and add respective trait configurations when creating the integration custom resource.
