[Redis] Support and cooperate with pool to implement a connection pool

[Avey777]

Describe the feature

Currently, reids cannot collaborate with the pool library to implement connection pooling

Use Case

pub fn (mut db DB) validate() !bool {
	db.ping()!
	return true
}

pub fn (mut db DB) reset() ! {
}

Proposed Solution

No response

	host     string
	port     u16
	password string
	tls      bool
	version  int = 2

	max_conns      int           = 100
	min_idle_conns int           = 10
	max_lifetime   time.Duration = 60 * time.minute
