:param instance_name: The name of the instance.
:param location: The Cloud Data Fusion location in which to handle the request.
:param namespace: If your pipeline belongs to a Basic edition instance, the namespace ID

can create a namespace.

:param impersonation_chain: Optional service account to impersonate using short-term
credentials, or chained list of accounts required to get the access_token
of the last account in the list, which will be impersonated in the request.
If set as a string, the account must grant the originating account
the Service Account Token Creator IAM role.

Service Account Token Creator IAM role to the directly preceding identity, with first
