support for stdin_open and tty keys

[concaf]

Hi,

My docker-compose.yml looks something like -

version: "2"
services:
  client:
     image: registry.centos.org/centos/centos:7
     stdin_open: true
     tty: true

kompose up gives me -

WARN[0000] Unsupported stdin_open key - ignoring        
WARN[0000] Unsupported tty key - ignoring               
WARN[0000] [client] Service cannot be created because of missing port. 
We are going to create Kubernetes Deployments, Services and PersistentVolumeClaims for your Dockerized application. 
If you need different kind of resources, use the 'kompose convert' and 'kubectl create -f' commands instead. 

INFO[0000] Successfully created Deployment: client      

Your application has been deployed to Kubernetes. You can run 'kubectl get deployment,svc,pods,pvc' for details.

Since these keys are unsupported, the pod goes from Running to Completed to CrashLoopBackOff

$ kubectl get pods -w
NAME                      READY     STATUS              RESTARTS   AGE
client-2474090665-o7wdc   0/1       ContainerCreating   0          1s
NAME                      READY     STATUS      RESTARTS   AGE
client-2474090665-o7wdc   0/1       Completed   0          1s
client-2474090665-o7wdc   0/1       Completed   1         2s
client-2474090665-o7wdc   0/1       CrashLoopBackOff   1         3s
client-2474090665-o7wdc   0/1       Completed   2         16s

It would be great if stdin_open and tty could be supported.

Here is the equivalent in Kubernetes world -

apiVersion: extensions/v1beta1
kind: Deployment
...
spec:
...
  template:
    metadata:
    ...
    spec:
      containers:
      - stdin: true
        tty: true
        image: registry.centos.org/centos/centos:7
