Updated docker logs timestamp to RFC3339 

Currently the docker logs timestamp flag generates log entries like:

    $ sudo docker logs -ft daemon_dave
    [May 10 13:06:17.934] hello world

It uses Go's StampMilli timestamp to generate the timestamp. The entry
is also wrapped in [ ].

This is non-standard operational timestamp and one that will require
custom parsing.

The new timestamp is RFC3999Nano and generates entries like:

    2014-05-10T17:42:14.999999999Z07:00 hello world

These are readily parsed by tools like ELK.

Passing a negative number or a non-integer to `--tail` is invalid and the
value is set to `all` in that case. This behavior may change in the future.
The `docker logs --timestamp` commands will add an RFC3339Nano
timestamp, for example `2014-05-10T17:42:14.999999999Z07:00`, to each
log entry.
