Similar to fs.Duration but parses into a timestamp instead
Supports parsing from:
* Any of the date formats in parseTimeDates
* A time.Duration offset from now
* parseDurationSuffixes offset from now
Before this change if the timezone was omitted in a
--min-age/--max-age time specifier then rclone defaulted to a UTC
timezone.
This is documented as using the local timezone if the time zone
specifier is omitted which is a much more useful default and this
patch corrects the implementation to agree with the documentation.

Before this change options were read and set in native format. This
means for example nanoseconds for durations or an integer for
enumerated types, which isn't very convenient for humans.
This change enables these types to be set with a string with the
syntax as used in the command line instead, so `"10s"` rather than
`10000000000` or `"DEBUG"` rather than `8` for log level.
TestParseDuration relied on an elapsed time calculation which
would vary based on the system local time. Fix the test by not relying
on the system time location. Also make the test more deterministic
by injecting time in tests rather than using system time.
Fixes#4529.
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
