Allow arguments to be passed when executing an enrichment connector

[nino-filigran]

Use case

This could make it possible to change the behavior, target, parameters, etc. of an enrichment connector at runtime. Example:

• Be able to dynamically select an index in ELK when calling it.
• Give the API key to be used by the connector to query the external source.
• Add execution code to define the action to be performed with the data sent to the integrated solution.
