chore: abstract dtos to encompass a wider range of use cases and fix for out of band proof requests

Description

Create generic DTOs for:

• Connection records

• Connection references

• Credential records

• Credential references

• Schema records

• Schema references

• Credential Definition records

• Credential Definition references

• Generic ID request dto

Other:

• Increase the NATS retries to 5 with 1 min between.
• Fix for waitForProofExchangeRecordSubject BehaviorSubject instead of ReplySubject. Because of this with multiple request for accept oob proof, it was working with the first values.

Checklist

• I have updated the documentation (if necessary)
• I have added unit tests for new functionality (if applicable)
• My code follows the style guidelines of this project
• I have tested this code on my local machine before submitting this MR
