feat: support more type to admin/config/set

add identity_ldap, notify_elasticsearch support.

How to test it:
pkg/utils/miniojob/minioJob_test.go should cover it.

{
			name: "notify_mysql",
			args: map[string]string{
				"webhookName": "notify_mysql",
				"dsn_string":  "username:password@tcp(mysql.example.com:3306)/miniodb",
				"table":       "minioevents",
				"format":      "namespace",
			},
			expectCommand:    "myminio notify_mysql dsn_string=\"username:password@tcp(mysql.example.com:3306)/miniodb\" format=\"namespace\" table=\"minioevents\"",
			expectFileNumber: 0,
		},
		{
			name: "notify_amqp",
			args: map[string]string{
				"webhookName": "notify_amqp:primary",
				"url":         "user:password@amqp://amqp-endpoint.example.net:5672",
			},
			expectCommand:    "myminio notify_amqp:primary url=\"user:password@amqp://amqp-endpoint.example.net:5672\"",

		},
		{
