As discussed in the meeting, two small changes are needed:

• generate test data dynamically (and delete the test configuration file)
• introduce a new boolean parameter in the config file, e.g. clientSpecific, and use it to determine if a default UKI should be served or a boot service serving client-specific UKIs (as the BootOperator) should be targeted

Thanks for the PR.

I did some small changes before the merging:

• fixed some wording
• reshuffeled some functions around, so the plugin looks similar to others
• fixed the TestWrongArgs test, which was broken
• refactored the client-specific tests, deduplicated some code
