【标题】
解决分布式锁超时时间与lockwait_timeout参数设置不符的问题

【实现内容】:
解决分布式锁超时时间与lockwait_timeout参数设置不符的问题

【根因分析】:
分布式锁加锁时未与lockwait_timeout参数比较，因此超时时间不受lockwait_timeout参数控制

【实现方案】:
加锁时等待时间与lockwait_timeout比较，超过该时间认定为加锁超时

【关联需求或issue】:
#I642AE:【测试类型：SQL功能】【测试版本：3.1.1】 【资源池化】锁等待超时，主节点获取X锁，备节点获取S锁，锁冲突，等待锁超时时间备节点处于等待状态

    a.备机加锁超时场景
    step1:主机端
[chendong@openGauss37 Thu Dec 01 20:28 dev]$ gsql -d postgres -p 12580 -r
gsql ((openGauss 3.1.0 build b8672a02) compiled at 2022-12-01 20:12:25 commit 0 last mr  debug)
Non-SSL connection (SSL connection is recommended when requiring high-security)
Type "help" for help.

openGauss=# show lockwait_timeout;
 lockwait_timeout
------------------
 5s
(1 row)

openGauss=# begin;
BEGIN
openGauss=# truncate student;
TRUNCATE TABLE

step2:备机端
