A new command to add K8s component to the Devfile from file

[valaparthvi]

/kind feature

Which functionality do you think we should add?

Add a new command to odo that will add K8s component to the Devfile from a file.

odo add component --type k8s --from-file <file>

Why is this needed?

This command might be helpful in cases where you need to modify the Devfile to add a K8s resource without doing so manually.
For e.g., defining a DB microservice inside Devfile that the application can connect to via ServiceBinding; odo will ensure the microservice is created for a successful bind.
Using the command will avoid having to use kubectl or oc client to create the service as well.
