Support loading dynamic plugin instances from dynamic configurations #6140
Description
Is your feature request related to a problem? Please describe.
The work contributed in #6138 does not support writing dynamic tests. This is exhibited in the grok processor integration tests.
Describe the solution you'd like
Find an approach to loading configurations more dynamically and allowing plugin authors to write @ParameterizedTest tests that operate on different plugin configurations.
Additional context
See GrokProcessorIT #6138 for the classic tests that couldn't be updated.
