[feature](ui) web profile download use plain text

[Mryange]

Proposed changes

download the plain text of the profile, reduce the overhead of string replace , converting JSON format.

    @RequestMapping(path = "/query_profile/{" + ID + "}", method = RequestMethod.GET)
    public Object profile(@PathVariable(value = ID) String id) {
        String profile = ProfileManager.getInstance().getProfile(id);
        if (profile == null) {
            return ResponseEntityBuilder.okWithCommonError("ID " + id + " does not exist");
        }
        profile = profile.replaceAll("\n", "</br>");
        profile = profile.replaceAll(" ", "&nbsp;&nbsp;");
        return ResponseEntityBuilder.ok(profile);
    }
