Creates a new Data Pipelines instance from the Data Pipelines API.
:param body: The request body (contains instance of Pipeline). See:
https://cloud.google.com/dataflow/docs/reference/data-pipelines/rest/v1/projects.locations.pipelines/create#request-body
:param project_id: The ID of the GCP project that owns the job.
:param location: The location to direct the Data Pipelines instance to (for example us-central1).
:param gcp_conn_id: The connection ID to connect to the Google Cloud
Platform.
: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.
If set as a sequence, the identities from the list must grant
Service Account Token Creator IAM role to the directly preceding identity, with first
account from the list granting this role to the originating account (templated).
.. warning::
This option requires Apache Beam 2.39.0 or newer.
Returns the created Data Pipelines instance in JSON representation.
