full idempotence (for example when client call times out repeating the request
with the same request id will not create a new instance template again)
It should be in UUID format as defined in RFC 4122
:param gcp_conn_id: The connection ID used to connect to Google Cloud. Defaults to 'google_cloud_default'.
:param api_version: API version used (for example v1 - or beta). Defaults to v1.
:param impersonation_chain: 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

"""
Deletes an Instance Group Managers.
Deleting an Instance Group Manager is permanent and cannot be undone.
.. seealso::
For more information on how to use this operator, take a look at the guide:
:ref:`howto/operator:ComputeEngineDeleteInstanceGroupManagerOperator`
:param resource_id: Name of the Instance Group Managers.
:param project_id: Google Cloud project ID where the Compute Engine Instance Group Managers exists.
If set to None or missing, the default project_id from the Google Cloud connection is used.
:param request_id: Unique request_id that you might add to achieve
full idempotence (for example when client call times out repeating the request
with the same request id will not create a new Instance Group Managers again)
It should be in UUID format as defined in RFC 4122
:param gcp_conn_id: The connection ID used to connect to Google Cloud. Defaults to 'google_cloud_default'.
:param api_version: API version used (for example v1 - or beta). Defaults to v1.
:param impersonation_chain: 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).
:param retry: A retry object used to retry requests. If `None` is specified, requests
will not be retried.
:param timeout: The amount of time, in seconds, to wait for the request to complete.
Note that if `retry` is specified, the timeout applies to each individual attempt.
:param metadata: Additional metadata that is provided to the method.
