Error Prevention Refactoring

[Angie-Zhang]

Meta Feature https://github.com/opensearch-project/index-management/issues/587

Based on analysis and implementation of actions under Error Prevention framework, we discover that:

1. Some common methods can be implemented at abstract level.
2. We also need a common logic to validate index type.
3. Validation passed message is not necessary, we can remove it.

Thus we need refactoring the code structure for Error Prevention.
