-Parse string to `Duration` . The String value unit support for one of:[y,mon,w,d,h,m,s]
-- y:Year. Support string value: ["y" | "year" | "Y" | "YEAR" | "Year"]. e.g. 1y
-- mon:Month.Support string value: ["mon" | "MON" | "Month" | "month" | "MONTH"]. e.g. 1mon
-- w:Week.Support string value: ["w" | "W" | "Week" | "WEEK" | "week"]. e.g. 1w
-- d:Day.Support string value: ["d" | "D" | "Day" | "DAY" | "day"]. e.g. 1d
-- h:Hour.Support string value: ["h" | "H" | "Hour" | "HOUR" | "hour"]. e.g. 1h
-- m:Minute.Support string value: ["m" | "M" | "Minute" | "MINUTE" | "minute"]. e.g. 1m
-- m:Second.Support string value: ["s" | "S" | "Second" | "SECOND" | "second"]. e.g. 1s
