[Feature Request] Support argument type 'organization' and 'organizations'

[bartvanb]

Problem description
Some algorithms require an organization id (or multiple) as input argument. For a novice user, it may be difficult to determine which IDs to supplement.

Desired solution
If the algorithm store API indicates a function argument is of type organization, show a dropdown from which to select an organization. If list[organization], allow to select multiple.
When sending the task to the backend, add the organization ids in the appropriate place.

Note: we may also need to specify type list, and then probably list[str], list[int] etc. But maybe we can get away with using a JSON type there
