Feature Request

Instead of

// RetryAfterErrorPeriod is the time that will be waited when an unexpected error happens before retry
	RetryAfterErrorPeriod types.Duration `mapstructure:"RetryAfterErrorPeriod"`
	// MaxRetryAttemptsAfterError is the maximum number of consecutive attempts that will happen before panicing.
	// Any number smaller than zero will be considered as unlimited retries
	MaxRetryAttemptsAfterError int `mapstructure:"MaxRetryAttemptsAfterError"`

Use

// RetriesPolicy is the configuration of maxRetries and delay between retries
	// that will be used for retrying operations in case of errors
	RetriesPolicy aggkitcommon.RetryPolicyGenericConfig `mapstructure:"RetriesToBuildAndSendCertificate"`	

rh, err := cfg.RetriesPolicy.NewRetryHandler()
