As an User
I want to know a.s.a.p. that I didn't gave the correct execution configuration key/value pairs for the given pipeline definition
so I don't have partly executed pipelines before I notice the error

Acceptance criteria

• Should verify and validate provided execution configuration against the pipeline definition before executing the pipeline
• Execution should fail when execution configuration is incorrect
• Fail message should provide details on:
  • Which key it failed on
  • Why it failed on that key, eg.:
    • Key provided but not expected
    • Required key not provided
    • Value of key invalid, incl. reason when possible
• Should fail only after all execution configuration is verified
• Fail message should contain all execution configuration failures

Implementation ideas:

• Implement multiple phases of execution, eg:
  • Validation phase, that executes the configuration validation as described by this story
  • Execution phase, that executes the pipeline with the provided configuration
