Request to list active breakpoints.
.. attribute:: debuggee_id
Required. Identifies the debuggee.
A token that, if specified, blocks the method call until the
list of active breakpoints has changed, or a server-selected
timeout has expired. The value should be set from the
``next_wait_token`` field in the last response. The initial
value should be set to ``"init"``.
If set to ``true`` (recommended), returns
``google.rpc.Code.OK`` status and sets the ``wait_expired``
response field to ``true`` when the server-selected timeout
If set to ``false`` (deprecated), returns
``google.rpc.Code.ABORTED`` status when the server-selected
timeout has expired.
