Improve readability of context schema

[mkuziemko]

Description

Changes proposed in this pull request:

• changes the type of contextSchema from string to object for in hub-js
• fixes tests in hub-js
• correction of the creation of the test storage TypeInstance

Testing

Using test backend storage TypeInstance:

1. Checkout this PR
2. Create cluster using DISABLE_MONITORING_INSTALLATION=true USE_TEST_SETUP=true make dev-cluster
3. Change manifests source to my branch:

   kubectl set env deploy/capact-hub-public -n capact-system -c hub-public-populator MANIFESTS_SOURCES="github.com/mkuziemko/hub-manifests?ref=fix_context_schema"

4. Create a test storage TypeInstance where the contextSchema is an object:

   cat > /tmp/storage-ti.yaml << ENDOFFILE
   typeInstances:
   - alias: "helm-storage"
   typeRef:
   path: cap.type.capactio.capact.validation.storage
   revision: 0.1.0
   value:
   acceptValue: true
   url: capact-test-storage-backend.capact-system:50051
   contextSchema: {
     "\$schema": "http://json-schema.org/draft-07/schema",
     "type": "object",
     "required": [
       "provider"
     ],
     "properties": {
       "provider": {
         "\$id": "#/properties/context/properties/provider",
         "type": "string",
         "enum": [
           "aws_secretsmanager",
           "dotenv"
         ]
       }
     },
     "additionalProperties": false
   }
   ENDOFFILE

   export STORAGE_TI=$(capact ti create -f /tmp/storage-ti.yaml -ojson | jq -r '.[] | select(.alias == "helm-storage") | .id')

5. Create a download TypeInstance that uses this test storage backend:

   cat > /tmp/download-ti.yaml << ENDOFFILE
   typeInstances:
   - alias: "download"
   typeRef:
   path: cap.type.capactio.capact.validation.download
   revision: 0.1.0
   value:
   key: "true"
   backend:
   context:
     provider: dotenv
   id: $STORAGE_TI
   ENDOFFILE
   export DOWNLOAD_TI=$(capact ti create -f /tmp/download-ti.yaml -ojson | jq -r '.[] | select(.alias == "download") | .id')

6. Try one more time but in this case with an incorrect provider - it should correct read the contextSchema object and reject the request:

   cat > /tmp/download-ti.yaml << ENDOFFILE
   typeInstances:
   - alias: "download"
   typeRef:
   path: cap.type.capactio.capact.validation.download
   revision: 0.1.0
   value:
   key: "true"
   backend:
   context:
     provider: test
   id: $STORAGE_TI
   ENDOFFILE
   export DOWNLOAD_TI=$(capact ti create -f /tmp/download-ti.yaml -ojson | jq -r '.[] | select(.alias == "download") | .id')

   Error output message:

   Error: while executing mutation to create TypeInstances: All attempts fail:
   #1: graphql: failed to create the TypeInstances: 2 error occurred:
   * Error: External backend "2cc59261-41d4-4cd2-a96c-164bca9378b9": invalid input: context/provider must be equal to one of the allowed values
   * Error: rollback externally stored values: External backend "2cc59261-41d4-4cd2-a96c-164bca9378b9": invalid input: context/provider must be equal to one of the allowed values

Install Mattermost using the Helm storage:

7. Create Helm storage input params:

   cat > /tmp/helm-storage-input-params.yaml << ENDOFFILE
   input-parameters: {}
   # Optional input parameters:
   # version: 0.6.0-bf8d006
   ENDOFFILE

8. Follow the instruction for installation of the Helm storage from here and update the policy
9. Follow the instruction for installation of the Mattermost from here
