    Parse GEP-2257 Duration format to a datetime.timedelta object.

    The GEP-2257 Duration format is a restricted form of the input to the Go
    time.ParseDuration function; specifically, it must match the regex
    "^([0-9]{1,5}(h|m|s|ms)){1,4}$".

    See https://gateway-api.sigs.k8s.io/geps/gep-2257/ for more details.

    Input: duration: string
    Returns: datetime.timedelta

    Raises: ValueError on invalid or unknown input

    Examples:
    >>> parse_duration("1h")
    datetime.timedelta(seconds=3600)
    >>> parse_duration("1m")
    datetime.timedelta(seconds=60)
    >>> parse_duration("1s")
    datetime.timedelta(seconds=1)
    >>> parse_duration("1ms")
    datetime.timedelta(microseconds=1000)
    >>> parse_duration("1h1m1s")
    datetime.timedelta(seconds=3661)
    >>> parse_duration("10s30m1h")
    datetime.timedelta(seconds=5410)

    Units are always required.
    >>> parse_duration("1")
    Traceback (most recent call last):
        ...
    ValueError: Invalid duration format: 1

    Floating-point and negative durations are not valid.
    >>> parse_duration("1.5m")
    Traceback (most recent call last):
        ...
    ValueError: Invalid duration format: 1.5m
    >>> parse_duration("-1m")
    Traceback (most recent call last):
        ...
    ValueError: Invalid duration format: -1m

    Format a datetime.timedelta object to GEP-2257 Duration format.

    The GEP-2257 Duration format is a restricted form of the input to the Go
    time.ParseDuration function; specifically, it must match the regex
    "^([0-9]{1,5}(h|m|s|ms)){1,4}$".

    See https://gateway-api.sigs.k8s.io/geps/gep-2257/ for more details.

    Input: duration: datetime.timedelta

    Returns: string

    Raises: ValueError if the timedelta given cannot be expressed as a
    GEP-2257 Duration.

    Examples:
    >>> format_duration(datetime.timedelta(seconds=3600))
    '1h'
    >>> format_duration(datetime.timedelta(seconds=60))
    '1m'
    >>> format_duration(datetime.timedelta(seconds=1))
    '1s'
    >>> format_duration(datetime.timedelta(microseconds=1000))
    '1ms'
    >>> format_duration(datetime.timedelta(seconds=5410))
    '1h30m10s'

    The zero duration is always "0s".
    >>> format_duration(datetime.timedelta(0))
    '0s'

    Sub-millisecond precision is not allowed.
    >>> format_duration(datetime.timedelta(microseconds=100))
    Traceback (most recent call last):
        ...
    ValueError: Cannot express sub-millisecond precision in GEP-2257: 0:00:00.000100

    Negative durations are not allowed.
    >>> format_duration(datetime.timedelta(seconds=-1))
    Traceback (most recent call last):
        ...
    ValueError: Cannot express negative durations in GEP-2257: -1 day, 23:59:59
