Bug: Application terminates because of casting error

[capt4ce]

Description

Returning status.Error() in P2P makes it un-castable to blocker that makes a few points in the code prone to error as P2P is essentially consumed by the same application in other node

Steps to reproduce

Try running this code isolated, it should return the same result:

package main

import (
	"fmt"

	"github.com/zoobc/zoobc-core/common/monitoring"
	"google.golang.org/grpc/codes"
	"google.golang.org/grpc/status"
)

type (
	TypeBlocker string

	Blocker struct {
		Type    TypeBlocker
		Message string
	}
)

var (
	ServiceErr                TypeBlocker = "ServiceErr"
	DBErr                     TypeBlocker = "DBErr"
	DBRowNotFound             TypeBlocker = "DBRowNotFound"
	BlockErr                  TypeBlocker = "BlockErr"
	BlockNotFoundErr          TypeBlocker = "BlockNotFoundErr"
	RequestParameterErr       TypeBlocker = "RequestParameterErr"
	AppErr                    TypeBlocker = "AppErr"
	AuthErr                   TypeBlocker = "AuthErr"
	ValidationErr             TypeBlocker = "ValidationErr"
	DuplicateMempoolErr       TypeBlocker = "DuplicateMempoolErr"
	DuplicateTransactionErr   TypeBlocker = "DuplicateTransactionErr"
	ParserErr                 TypeBlocker = "ParserErr"
	ServerError               TypeBlocker = "ServerError"
	SmithingErr               TypeBlocker = "SmithingErr"
	ZeroParticipationScoreErr TypeBlocker = "ZeroParticipationScoreErr"
	ChainValidationErr        TypeBlocker = "ChainValidationErr"
	P2PNetworkConnectionErr   TypeBlocker = "P2PNetworkConnectionErr"
	SmithingPending           TypeBlocker = "SmithingPending"
	TimeoutExceeded           TypeBlocker = "TimeoutExceeded"
)

func NewBlocker(typeBlocker TypeBlocker, message string) error {
	monitoring.IncrementBlockerMetrics(string(typeBlocker))
	return Blocker{
		Type:    typeBlocker,
		Message: message,
	}
}

func (e Blocker) Error() string {
	return fmt.Sprintf("%v: %v", e.Type, e.Message)
}

func main() {
	err := status.Error(codes.Internal, "test")
	errCasted := err.(Blocker)
	fmt.Println(errCasted.Error())
}

Expected behavior

the casting should not produce error that would make the node terminate
