pika parameters are compatible with sentinel

Which PikiwiDB functionalities are relevant/related to the feature request?

No response

Description

pika 缺少 master_link_down_since_seconds 指标，含义为 slave 与 master 的链接出现异常之后，slave开始计时。
sentinel选主时就不会选择master_link_down_since_seconds > master宕机时间的 slave 节点，可以更加准确的进行选主。

offset 格式不同
redis ：slave_repl_offset:
pika ：db0 binlog_offset=0 0
是否可以抽象出一个 slave_repl_offset

您好，请问您说的sentinel是pika自己设计的codis中集成的哨兵还是说redis原生的哨兵呢？我这边在搭建最基础的Master-Slave式的的pika服务时，发现配合redis原生sentinel不能实现故障转移。

Hello, is the sentinel you are talking about the sentinel integrated in codis designed by pika itself, or the sentinel native to redis? When I was building the most basic Master-Slave-style pika service, I found that failover could not be achieved with redis's native sentinel.
