feat: Plat-6681 expose crud api endpoints

[zeljkoX]

Summary

Parent branch that contains all work regarding exposing CRUD endpoints.

Work included:

• Introduced CRUD API endpoints for signers, notifications and relayers
• Removed vault_cloud signer support due to service being deprecated
• Implemented logic for securely persisting secrets in redis
• Refactored models to use domain models for validations given we have two entry points (config, api request). Request and Config models are converted to domain and validated.
• Allowed starting service without requiring resources to be defined in config file
• Storage agnostic transaction expiration logic
• Documentation

It should be merged once all CRUD endpoints are implemented.
