[Improve][Manager] Simplify code for InLong group management

[aloyszhang]

Description

In the manager, I found some duplicated interfaces, e.g. InlongGroupService

    /**
     * Save inlong group info.
     *
     * @param groupInfo group request need to save
     * @param operator name of operator
     * @return inlong group id after saving
     */
    String save(@Valid @NotNull(message = "inlong group request cannot be null") InlongGroupRequest groupInfo,
            String operator);

    /**
     * Save inlong group info.
     *
     * @param groupInfo group request need to save
     * @param opInfo userinfo of operator
     * @return detail of inlong group
     */
    String save(@Valid @NotNull(message = "inlong group request cannot be null") InlongGroupRequest groupInfo,
            UserInfo opInfo);

The only different is the second parameter, one is operator and the other is UserInfo, and the real usage of UserInfo is to get the operator by UserInfo#getName() .
So, this two methods are same essentially.

We can simplify the code here by unifying the two methods to one.
