Support extra advanced parameters for the Dolos analysis in the API

The Dolos API to create a new report is currently very simple: the caller should upload a ZIP-file, and can optionally specify a report name and programming_language.

Some use-case require more flexibility to change algorithm parameters and/or submit code to ignore.

To support this, the API should be extended to pass these options to the Dolos CLI. Special care needs to be taken to sanitize these options correctly.
