feat: support format flag to support json content for the head commands

[flywukong]

Description

1) support --format json flag to return the JSON format of head object/bucket/group 2) fix the logic of uploading the folder by only uploading the last level directory of the file directory structure. For example , if using "object put aaa/bbb/ccc--recursive " to upload folder "ccc" , it will create it should just create "ccc/ " and the sub folders, not "aaa/bbb/ccc/"

Rationale

support json to show the meta

Example

./gnfd-cmd  object head --format json gnfd://diiik1/test8911
