  brief: Add IAM policy binding to a Compute Engine instance template.
  description: |
    Add an IAM policy binding to the IAM policy of a Compute Engine instance template. One binding consists of a member,
    a role, and an optional condition.

  examples: |
    To add an IAM policy binding for the role of 'roles/compute.admin' for the user 'test-user@gmail.com'
    with instance template 'my-template', run:

      $ {command} my-template --member='user:test-user@gmail.com' --role='roles/compute.admin'

    To add an IAM policy binding which expires at the end of the year 2018 for the role of
    'roles/compute.admin' and the user 'test-user@gmail.com' with instance template 'my-template', run:

      $ {command} my-template --member='user:test-user@gmail.com' --role='roles/compute.admin' --condition='expression=request.time < timestamp("2019-01-01T00:00:00Z"),title=expires_end_of_2018,description=Expires at midnight on 2018-12-31'

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