Backward compatible version of #62 -- This version does not change the
default behavior. Users must opt in to new behavior.

This patch updates the file sink to allow not appending the timestamp
on the current log file. In this mode the timestamp is only appended
when the file is rotated.

This matches the behavior:

The following example configures a destination called "My Sink" which
stores audit events at the file /tmp/audit.json.

Nomad's documentation is a little vague but implies the prior behavior
of always appending a timestamp.

This matches the behavior:

- Implemented in Nomad v1.1.4 with hashicorp/nomad#11070
- Requested in hashicorp/nomad#11061

Nomad's documentation is a little vague but implies the prior behavior
of always appending a timestamp.
While Go compares time using a monotonic clock that only prevents time from
moving *backward,* it does *not* guarantee time will move forward
between subsequent calls to `time.Now()`. The After assertion failed in
a test run on Github because it is missing the `Equal` comparison on the
preceeding assertion.
