Allow parameters in command definitions in runner.yml

[donquixote]

In #25 the option was added to define commands inside the runner.yml(.dist) file.

It would be nice if we could also add parameters to those commands.

Currently this has to be defined like so, by specifying the full cli command as a single string:

commands:
  efd:build-themes:
  - "${runner.bin_dir}/run efd:npm-build --npm-dir=path/to/npm/root"

With support for parameters / arguments, it could look like this:

commands:
  efd:build-themes:
  -
    task: "run"
    command: "efd:npm-build"
    arguments: {npm-dir: "path/to/npm/root"}

(The example is inspired from this, https://github.com/ec-europa/ecdc-vaccine-reference/blob/6cf99aec072e0b6616cc6a0967be692692c53103/src/TaskRunner/Commands/EcdcBuildCommands.php#L71)

The relevant piece of code is in CollectionFactory::taskFactory()

(I am posting specific commit ids to be sure this link still points to the same piece of code in the future)

One could argue that the "old" version is actually shorter.
But the second version is more semantic and readable.

Those are more "options" than "arguments".

@donquixote the link you've provided in the description, is broken. Could you please send here the correct link or the code snippet. I would like to fill a PR.
