Error while loading an event should be clear and show exact message

[sakshiarora386]

Version Information

Godspeed Version: 2.5.3
CLI Version (if applicable): 2.9.7

Current Behavior

• When there is any error in event schema definition or function not found (authz or fn)
• Swagger is not hitting that api, if there was not responses added in schema definition
• when there was error in params format, then logs were not showing exact error message

Expected Behavior

• Show full error log and don't start the service

How will we Solve

• Show exact error with solution including documentation guides link.

Future Enhancement:

1. Use the existing schemas for event validations
2. Framework schemas will be loaded from gs-node-service like (event schema and config schema).
3. Datasource and eventsource yaml schemas will be loaded from (A) local src folder (eventsources or datasources)/types/{es_name}-schema.yaml} or (B) from respective plugin node_modules folder having name {es_name}-schema.yaml
4. Generated plugin instance yaml file should always load from this yaml schema file
5. If yaml schema for plugin is not found, then show a warning with appropriate message.
6. Create a guide in docs, how to add schema to plugin or your project folder
