Broken DB compatibility in image cache

[xpoback]

I know that this issue doesn't follow the guidelines, but whatever.
I would like to ask you guys to pay more attention on the things you do and, especially, release.

You've declared _fileExists() in app/code/Magento/Catalog/Model/Product/Image.php, why not to use it everywhere in the class.
Just a little change, absence of which creates big problems to me and other people, that want to save their cache images not on the same server.

Completely agree with the emotional part, however you could've also create a pull request into 2.1-develop as well, you know.
Just saying :)

@xpoback thank you for report. We will consider your suggestion. Also, feel free submit a pull request if this is a critical issue for you

The task, I was working on, has been finished long ago even with the problem described.
Since it wasn't a critical issue (just another plugin was needed), no PR will be created (cuz I'm lazy to look up what I did in April).
Thanks for your time and have a good day.
