Create dataset command

Proposed command

deploifai dataset create --name <name> --project <username/project>

We should refactor from deploifai data init command, which creates a dataset through the backend api. And also the --project option might not be necessary because we can assume the user is working from within a deploifai project, in which its id would have been saved in the local configuration file.

As discussed, a new dataset create command should be made which simply calls the backend server to create a new dataset resource. Project information should be obtained from the local config, and an existing cloud profile to create the dataset should be prompted for the user to select.
