Add more information to 'Deployment's in OpenShift generator

Currently, toolform is missing functionality to output the `strategy` and `triggers` blocks in **spec**, and also the `envFrom`, `args`, or `readinessProbe` blocks in **spec>template>spec>containers** of the `Deployment` sections of the generated OpenShift deployment file.

To illustrate, toolform currently produces deployments with the following sections:
```
apiVersion:
kind:
metadata:
annotations:
source.path:
project.artefact:
name:
spec:
replicas:
template:
metadata:
labels:
component:
spec:
containers:
-
image:
name:
imagePullPolicy:
ports:
- containerPort:
volumeMounts:
- name:
mountPath:
volumes:
- name:
persistentVolumeClaim:
claimName:
```
And the goal is to produce the following (asterisks indicate the missing lines):
```
apiVersion:

source.path:
project.artefact:
name:
spec:
strategy: *
