Improve devfile:generate command

[l0rd]

• Support config maps
• Better input sanity check: verify that a plugin provided as a parameter has a valid format
• Find a better way to generate src/api/devfile.ts (currently done via quicktype.io)
• complete devfile/generate.test.ts
  • make nock work
  • parse yaml output and verifies, for each kind, the number of items and the fields that should exist and those that should not.
• Add an e2e test:

  kubectl create namespace prod
  kubens prod
  kubectl apply -f https://raw.githubusercontent.com/sleshchenko/NodeJS-Sample-App/dockerCon/deploy_k8s.yaml
  chectl devfile:generate \
          --selector="app.kubernetes.io/name=employee-manager" \
          --language=typescript \
          --git-repo='https://github.com/sleshchenko/NodeJS-Sample-App.git'
  kubectl delete services --all -n prod
  kubectl delete deployment --all -n prod

• Support specifying multiple selectors (e.g. --selector="name=springboot" --selector="name=mysql")
• Support specifying multiple languages (e.g. --language=java --language=go)
• Support specifying multiple plugins
• Support --file as an alternative to --namespace as a source for k8s resources

@l0rd I think it makes sense to support generating a devfile from a file as well. For example, for this Demo project https://github.com/sleshchenko/NodeJS-Sample-App it would look like the following

chectl devfile:generate \
        --file=deploy_k8s.yaml
        --language=typescript \
        --git-repo='https://github.com/sleshchenko/NodeJS-Sample-App.git'

And then generated Devfile may reference this file instead of inlining content.
WDYT?

Good idea @sleshchenko I have updated the description
