LU03b - Custom agent (NYI)

^{Internal reference: learningunits/03-2.md}

1. I can set up a custom Jenkins agent as container.
2. I can push and pull Jenkins agent to my container-repository.
3. If there are any errors, I can analyze the error, suggest and test an initial workaround (troubleshooting).

1. NYI 01/02_Exercises/03-Exercise.md
2. If there is an error, read the message carefully, think about a solution and implement it.
