Hooray! You can now use workflows in Fission.

Usage:
```bash
# Setup a couple of Fission functions
https://raw.githubusercontent.com/fission/fission-workflows/master/examples/whales/fortune.sh > fortune.sh
https://raw.githubusercontent.com/fission/fission-workflows/master/examples/whales/whalesay.sh > whalesay.sh

fission env create --name binary --image fission/binary-env
fission fn create --name whalesay --env binary --deploy ./whalesay.sh
fission fn create --name fortune --env binary --deploy ./fortune.sh

# Setup a workflow using the workflow environment
curl https://raw.githubusercontent.com/fission/fission-workflows/master/examples/whales/fortunewhale.wf.yaml > fortunewhale.wf.yaml

fission fn create --name fortunewhale --env workflow --src ./fortunewhale.wf.yaml

# Invoke the workflow just like any other Fission function

curl $FISSION_ROUTER/fission-function/fortunewhale
```
