Integrate RedisStore from `echox/store` into abuse middleware's `NewMemoryCounter`

[its-ernest]

For multi-servers in production:
Proposed usage:

       e := echo.New()

	abuseStore := store.NewRedisCounter("localhost:XXXX")
	// Instant-ban on sensitive files, warn on API spam
	e.Use(abuse.New(abuse.Config{
		Store:     abuseStore,
		Threshold: 100,
		Rules: []abuse.Rule{
			// immediate ban for ANY attempt on .env
			{Path: "/.env", Score: 100},

			// heavy score only for POST requests to login (brute force protection)
			{Path: "/api/v1/login", Method: "POST", Score: 20},

			// light score for general API exploration
			{Path: "/api/v1/*", Method: "GET", Score: 2},
			{Path: "/api/v1/users", Method: "PUT", Score: 20},
		},
	}))
