Add cache helpers

[jeffprestes]

Add code below to Mercurius template generator to create cache.go file within lib/utils folder

package utils

import (
	"fmt"
	"log"
	"strconv"
	"time"

	"<mercurius' project package name>/lib/context"
)

/*
PutIntoCache puts a value at system's cache
*/
func PutIntoCache(key string, value interface{}) {
	s := fmt.Sprintf("%.0f", (time.Hour * 48).Seconds())
	timeout, _ := strconv.Atoi(s)

	err := PutIntoCacheWithTimeout(key, timeout, value)
	if err != nil {
		log.Printf("[PutIntoCache] Erro ao incluir no cache: [%s]. Key: [%s] - Value: [%v]\n", err.Error(), key, value)
	}
	log.Printf("[PutIntoCache] Cache inputed. Key: [%s] - Value: [%v]\n", key, value)
}

/*

*/
func PutIntoCacheWithTimeout(key string, timeoutInSeconds int, value interface{}) error {
	ctx := context.GetContext()
	cache := ctx.Cache

@jeffprestes done 9817b53c3c301c2b5fc6b1379e163d3f54b62d98now mercurius have a new package named helpers with these helpers. I change the package for better code organization.
