[Improvement] Kedge should block until application pod comes up

[hrishin]

Current Experience:
'kedge create ---' deploys the application on Kubernetes/OpenShift. But to check whether deployment is happening or not, the developer needs to check it through to Kubernetes/OpenShift (either login to console or query through CLI).
It always may not be the case that application deployment will get successful as well.

Would it be nice if kedge can wait till actually application pod comes up?
Meanwhile

• Kedge can fetch the build pod log if applicable
• Print initial application logs
• Can show if application development got succeed or failed

It could be an omnichannel experience for the developer without leaving the current window. :)
