### Description
hello:
I use apisix-dashboard to config one route, it could config Keepalive
Pool, such as:（the following config is in etcd）
`
{
"id": "414195977881125816",
"create_time": 1656409641,
"update_time": 1658299923,
"uri": "/get",
"name": "httpbin-test",
"methods": ["GET", "POST", "PUT", "DELETE", "PATCH", "HEAD",
"OPTIONS", "CONNECT", "TRACE"],
"upstream": {
"nodes": {
"httpbin.org:80": 1
},
"timeout": {
"connect": 6,
"send": 6,
"read": 6
},
"type": "roundrobin",
"scheme": "http",
"pass_host": "pass",
"keepalive_pool": {
"idle_timeout": 0,
"requests": 1000,
"size": 320
}
},
"status": 1
}
`
when I set idle_time is 0, according to
[https://github.com/apache/apisix-dashboard/issues/2294](url), the keepalive
should be closed, and when I set idle_time is 60s, I think it should open keep
alive pool，but what I find is in following source code:
apisix/balancer.lua -> method:set_current_peer(server, ctx)
[https://github.com/apache/apisix/blob/f5f402f4484dc09300860a1798e003410e1fb456/apisix/balancer.lua#L284](url)
`
function set_current_peer(server, ctx)
local up_conf = ctx.upstream_conf
local keepalive_pool = up_conf.keepalive_pool
if enable_keepalive then
if not keepalive_pool then
if not default_keepalive_pool then
`
I find whatever I set idle_time is 0 or 60s, the above **enable_keepalive**
is also null, so keep_alive is closed, the **enable_keepalive** is set in front
of balancer.lua
[https://github.com/apache/apisix/blob/f5f402f4484dc09300860a1798e003410e1fb456/apisix/balancer.lua#L20](url)
`
local balancer = require("ngx.balancer")
local enable_keepalive = balancer.enable_keepalive and is_http
`
so I want to know in what situation, the **enable_keepalive** cloud have
value? because there is no way to config this property. and how can I close
keep_alive in route, set idle_time is 0?
