class RemoveIamPolicyBinding(base.Command):
  """Remove IAM policy binding from an EkmConfig.

  Removes a policy binding from the IAM policy of a kms EkmConfig. A binding
  consists of at
  least one member, a role, and an optional condition.

  ## EXAMPLES
  To remove an IAM policy binding for the role of 'roles/editor' for the user
  'test-user@gmail.com' on the EkmConfig with location us-central1, run:

    $ {command} --location='us-central1' --member='user:test-user@gmail.com'
    --role='roles/editor'

  To remove an IAM policy binding with a condition of
  expression='request.time < timestamp("2023-01-01T00:00:00Z")',
  title='expires_end_of_2022',
  and description='Expires at midnight on 2022-12-31' for the role of
  'roles/editor'
  for the user 'test-user@gmail.com' on the EkmConfig with location us-central1,
  run:

    $ {command} --location='us-central1' --member='user:test-user@gmail.com'
    --role='roles/editor' --condition='expression=request.time <
    timestamp("2023-01-01T00:00:00Z"),title=expires_end_of_2022,description=Expires
    at midnight on 2022-12-31'

  To remove all IAM policy bindings regardless of the condition for the role of
  'roles/editor' and for the user 'test-user@gmail.com' on the EkmConfig with
  location us-central1, run:

    $ {command} laplace --location='us-central1'
    --member='user:test-user@gmail.com' --role='roles/editor' --all

  See https://cloud.google.com/iam/docs/managing-policies for details of
  policy role and member types.
