feat: add managed by score annotation to support humanitec UI warnings

[johanneswuerbach]

Add a "humanitec.io/managed-by": "score-humanitec" annotation to signal that workloads are managed by score and not inside the Humanitec UI.

Additionally add a new --workload-source-url parameter that allows link to the score file so developers can quickly find the file.

Description

What does this PR do?

Workloads that are managed by score can be manually edited in the humanitec app, and then the manual edit can be overridden with the next deployment. This change gives the user the ability to point to the location which manages the workload, and it will display the user a warning that the workload is managed by score (and will link to the path provided in the parameter)
