Add config validation and telemetry

[VipulMascarenhas]

Description

This PR adds the the following changes:

1. Validate model_type in config.json: If custom metadata has this attribute, then check if config.json is available in the user bucket where artifacts are loaded from.
2. Bug fix: after registering model, model card should return the readme from the user bucket instead of verified model bucket.
3. Record telemetry information after registering models.
4. Updated Unit Tests.
