Support -o json and -o name on get

[sderosiaux]

• supports -o or --output json|yaml|name (default yaml)
• the '---' is now at the beginning of each yaml document, not the end, to follow the standard practice
• the JSON is the one from the API, no reordering
• it works on get: on list and single item

Why?

Because JSON is more automatable (?) than YAML.

eg:

$ conduktor get Application -o json | jq -r '.[].metadata.name'
purchase-pipeline
tracker
support

Because single line is more readable at a glance than YAML: (the best thing will be when you can "get all" with that)

$ ./conduktor get ApplicationInstance -o name
ApplicationInstance/tracker-dev
ApplicationInstance/support-dev
ApplicationInstance/purchase-pipeline-dev

Examples:

• on one item:

$ ./conduktor get Application support -o json
{
  "apiVersion": "v1",
  "kind": "Application",
  "metadata": {
    "name": "support"
  },
  "spec": {
    "title": "The support",
    "description": "The support of our company",
    "owner": "support-project"
  }
}

• on a list:

./conduktor get Application -o json
[
  {
    "apiVersion": "v1",
    "kind": "Application",
    "metadata": {
      "name": "purchase-pipeline"
    },
    "spec": {
      "title": "Purchase pipeline",
      "description": "money money money",
      "owner": "admin"
    }
  },
  {
    "apiVersion": "v1",
    "kind": "Application",
    "metadata": {
      "name": "tracker"
    },
    "spec": {
      "title": "User tracking",
      "description": "Track our dear customers",
      "owner": "tracker-project"
    }
  },
  {
    "apiVersion": "v1",
    "kind": "Application",
    "metadata": {
      "name": "support"
    },
    "spec": {
      "title": "The support",
      "description": "The support of our company",
      "owner": "support-project"
    }
  }
]

• default behavior unchanged, yaml (except for the '---'):

$ conduktor get Application
---
apiVersion: v1
kind: Application
metadata:
    name: purchase-pipeline
spec:
    title: Purchase pipeline
    description: money money money
    owner: admin
---
apiVersion: v1
kind: Application
metadata:
    name: tracker
spec:
    title: User tracking
    description: Track our dear customers
    owner: tracker-project
---
apiVersion: v1
kind: Application
metadata:
    name: support
spec:
    title: The support
    description: The support of our company
    owner: support-project

Missing tests but I'm not sure if we already have some for get only

[strokyl]

Could be great to add some test in test_final_exec.sh
It won't test the output but at least that the command does not crash when using -o
