feat: create data connector in project

[olevski]

This is the initial implementation.

Things that are missing:

• no tests
• the way that data connectors in projects are displayed is not right
• the backend is still a bit wonky and will not support everything (i.e. launching sessions fails)

The PR changes make overall sense so far 👍 Some early comments inline.

In short, there is a better way to add types from the updated APIs from other repos branches, and there is some less-than-ideal prop drilling here -- tho the components you are touching here weren't the most straightforward and your solution looks acceptable in this case.

[lorenzo-cavazzi]

If these types are up-to-date in the renku-data-service branch feat-add-project-as-dc-owner-pt2, instead of creating an enhanced-api file, you should take the up-to-date spec file from there, overwrite the namespace.openapi.json file here and run the npm command npm run generate-api:namespaceV2.
We use the enhanced version mainly for extending the APIs -- usually transforming the response into a more convenient object (transformResponse) or using the tags to auto-refetch content (providesTags on GET and invalidatesTags on the other verbs)

They are not changed in the backend. But I think I will have to update them in the backend. For now I am kind of forcing the project namespace in a few places. And that is why I need this. I will remove this when it is fully integrated in the backend. I think I will be able to do this during the build.

I'm surprised this component named "Project NamespaceFormField" is already used for Data Connectors namespaces. I was tempted to suggest creating another component, or at least renaming and moving it to make it clear it's not only for Project namespaces.
We can keep it as is for now. Still, if the logic to extract Data connector namespaces gets more complicated later in the build, we might consider separating it so that we have less code for each entity (project vs data connector).
