[🔨 Enhancement]: Secrets Manager - add error handling and exceptions

[shahargl]

Current:

1. BaseSecretManager - read_secret, write_secret as abstract methods
2. Every deriving manager implements those functions
3. No error handling

Expected Behaviour

1. BaseSecretManager - _read_secret, _write_secret as abstract methods
2. BaseSecretManager - read_secret and writesecret which uses the `` methods with try/except
3. Every deriving manager implements error handling with at least PermissionError
