增加check接口，用于排查ck表在index pattern中不显示的问题

Describe the solution you'd like

通过接口/check/表名来访问，例如：/check/ops_test_all
返回结构如下：

{
    "index": "ops_test_all",
    "databaseUrls": [
        "jdbc:clickhouse://demo.test:80/ops"
    ],
    "directToEs": true,
    "hitTables": [],
    "inWhiteList": false,
    "whiteList": [
        "ops_test_all",
        "ops_test1_all"
    ],
    "sql": "SELECT name FROM system.tables WHERE database = 'ops'  AND name = 'ops_test_all'  "
}
