Repository: apache/camel-k (go)

Issue:
Stable container name
When camel-k creates a deployment, it sets the name of the container after the name of the integration instead, when a knative service is created, the container name is not set.

For better user experience it could be nice to:
- by default, set the name of the container to `integration-container` for deployments and knative services
- have an option to customize the container name `-t container.name=something`

Pull request:
Stable container name
Fixes #826
