[Feature] Add type for meta data of owner

[stevending1st]

Description

I think owner's meta data should add a type field to mark whether the owner is org or user.

e.g. https://[oss.x-lab.info/open_digger/github/X-lab2017/meta.json](https://oss.x-lab.info/open_digger/github/X-lab2017/meta.json)

{
    ...
    type: "org“
    ...
}

https://[oss.x-lab.info/open_digger/github/stevending1st/meta.json](https://oss.x-lab.info/open_digger/github/stevending1st/meta.json)

{
    ...
    type: "user"
    ...
}

Although github provides this interface, I still think it's a good feature.

The work has been done in #1332 , I will update the data before tomorrow.

But for this month, the type will only added into the accounts with exported repos. So if you get a meta data without type and repos field, it is a user account.

And for next month, the user type will also be added into the user accounts that has exported metrics but no exported repos.

This is really good news. Thank you very much for your work.
