feat(pkg): add pkg time

This package is used to control how we utilize the time package across
the Deis Platform, including application logs, component logs, API
datetime structures, etc.
I think the binary installer only installs it for your current architecture, so you'd have to compile Go from source a la

```
sudo su
curl -sSL https://golang.org/dl/go1.4.src.tar.gz | tar -v -C /usr/local -xz
cd /usr/local/go/src
./make.bash --no-clean
GOOS=linux GOARCH=amd64 ./make.bash --no-clean
```
