request help: radixtree_host_uri does not consider routing priority

[haifeng9414]

Issue description

Why does radixtree_host_uri.lua not set the priority when creating a route:

local radixtree_route = {
        paths = route.value.uris or route.value.uri,
        methods = route.value.methods,
        remote_addrs = route.value.remote_addrs
                       or route.value.remote_addr,
        vars = route.value.vars,
        filter_fun = filter_fun,
        handler = function (api_ctx)
            api_ctx.matched_params = nil
            api_ctx.matched_route = route
        end
    }

Is this a bug?

radixtree_uri.lua文件创建radixtree_router对象的时候设置了路由的priority属性，但是radixtree_host_uri.lua文件没有，如果我用radixtree_host_uri作为路由实现，配置两个域名和uri相同，优先级不同的路由，路由的优先级能起作用吗？
下面是两个文件创建radixtree_router对象的代码：

-- radixtree_uri.lua
core.table.insert(uri_routes, {
    paths = route.value.uris or route.value.uri,
    methods = route.value.methods,
    priority = route.value.priority, -- 这里设置了路由的优先级
    hosts = route.value.hosts or route.value.host,
    remote_addrs = route.value.remote_addrs
                   or route.value.remote_addr,
    vars = route.value.vars,
    filter_fun = filter_fun,
    handler = function (api_ctx)
        api_ctx.matched_params = nil
        api_ctx.matched_route = route
    end
})

-- radixtree_host_uri.lua
local radixtree_route = {
    paths = route.value.uris or route.value.uri,
    methods = route.value.methods,
    -- 这里没有设置路由的优先级
    remote_addrs = route.value.remote_addrs
                   or route.value.remote_addr,
    vars = route.value.vars,
    filter_fun = filter_fun,
    handler = function (api_ctx)
        api_ctx.matched_params = nil
        api_ctx.matched_route = route
    end
}
