[PLT-1018] Add dataset.set_iam_integration() to select/deselect integrations

[paulnoirel]

Currently, users can create datasets with the SDK but can't modify the integration outside of the UI. This makes migration projects tedious since no automation is possible.

The current method brings a quick solution to this problem.

With this new method it is possible to:

• Set IAM integration for integration id

# Get all IAM integrations
iam_integrations = client.get_organization().get_iam_integrations()

 # Get IAM integration id
iam_integration_id = [integration.uid for integration
   in iam_integrations
   if integration.name == "My S3 integration"][0]

dataset.add_iam_integration(iam_integration_id)

• Set IAM integration for IAM integration object

# Get all IAM integrations
iam_integrations = client.get_organization().get_iam_integrations()

 # Get IAM integration object
iam_integration = [integration.uid for integration
   in iam_integrations
   if integration.name == "My S3 integration"][0]
 
dataset.add_iam_integration(iam_integration)

• Remove IAM integration

dataset.remove_iam_integration()

Comments left. LGTM in concept, but some styling/consistency stuff.
