    for the user 'test-user@gmail.com' with backup 'example-backup' and
    instance 'example-instance', run:

        $ gcloud alpha spanner backups remove-iam-policy-binding \
            example-backup --instance='example-instance' \
            --member='user:test-user@gmail.com' \
            --role='roles/spanner.backupAdmin'

    To remove an IAM policy binding which expires at the end of the year 2018
    for the role of 'roles/spanner.backupAdmin' and the user
    'test-user@gmail.com' with backup 'example-backup' and instance
    'example-instance', run:

        $ gcloud alpha spanner backups remove-iam-policy-binding \
            example-backup --instance='example-instance' \
            --member='user:test-user@gmail.com' \

POSITIONAL ARGUMENTS
     Backup resource - The Cloud Spanner backup to remove the IAM policy
     binding from. The arguments in this group can be used to specify the
     attributes of this resource. (NOTE) Some attributes are not given
     arguments in this group but can be set in other ways. To set the project
     attribute:
      ◆ provide the argument backup on the command line with a fully
        specified name;
      ◆ set the property core/project;
      ◆ provide the argument --project on the command line.

     This must be specified.

       BACKUP
          ID of the backup or fully qualified identifier for the backup. To set
          the backup attribute:
          ▸ provide the argument backup on the command line.

          This positional must be specified if any of the other arguments in
          this group are specified.

       --instance=INSTANCE
          The name of the Cloud Spanner instance.

          To set the instance attribute:
          ▸ provide the argument backup on the command line with a fully
            specified name;
          ▸ provide the argument --instance on the command line;
          ▸ set the property spanner/instance.

REQUIRED FLAGS
     --member=PRINCIPAL
        The principal to remove the binding for. Should be of the form
        user|group|serviceAccount:email or domain:domain.

        Examples: user:test-user@gmail.com, group:admins@example.com,
        serviceAccount:test123@example.domain.com, or
        domain:example.domain.com.

        Deleted principals have an additional deleted: prefix and a ?uid=UID
        suffix, where UID is a unique identifier for the principal. Example:
        deleted:user:test-user@gmail.com?uid=123456789012345678901.

        Some resources also accept the following special values:
        ◆ allUsers - Special identifier that represents anyone who is on the
          internet, with or without a Google account.
        ◆ allAuthenticatedUsers - Special identifier that represents anyone
          who is authenticated with a Google account or a service account.

     --role=ROLE
        The role to remove the principal from.

OPTIONAL FLAGS
     At most one of these can be specified:

       --all
          Remove all bindings with this role and principal, irrespective of any
          conditions.

       --condition=[KEY=VALUE,...]
          The condition of the binding that you want to remove. When the
          condition is explicitly specified as None (--condition=None), a
          binding without a condition is removed. Otherwise, only a binding
          with a condition that exactly matches the specified condition
          (including the optional description) is removed. For more on
          conditions, refer to the conditions overview guide:
          https://cloud.google.com/iam/docs/conditions-overview

          When using the --condition flag, include the following key-value
          pairs:

           expression
              (Required) Condition expression that evaluates to True or False.
              This uses a subset of Common Expression Language syntax.

              If the condition expression includes a comma, use a different
              delimiter to separate the key-value pairs. Specify the delimiter
              before listing the key-value pairs. For example, to specify a
              colon (:) as the delimiter, do the following:
              --condition=^:^title=TITLE:expression=EXPRESSION. For more
              information, see
              https://cloud.google.com/sdk/gcloud/reference/topic/escaping.

           title
              (Required) A short string describing the purpose of the
              expression.

           description
              (Optional) Additional description for the expression.

       --condition-from-file=CONDITION_FROM_FILE
          Path to a local JSON or YAML file that defines the condition. To see
          available fields, see the help for --condition.
