SFTP file sync

[ELigoP]

Problem Statement

Currently SFTP file sync is not implemented. It would be great to just enter some sftp host, username, password/identity key and have easily accessible sync from anywhere, which is simple as DropBox and private as NextCloud.

:grey_question: Possible Solution

On Linux PC, I can workaround using sshfs mounting remote dirs. That's how I do it now between two PCs. But for Android it does not work (see below). So it is better to just add some SSH library, that will do all connection itself.

:arrow_heading_up: Describe alternatives you've considered

I've tried using programs that are supposed to mount remote folders, but it didn't work. For SSHFS you need rooted device, and Android apps like CIFS Documents Provider provide a 'mounted as local storage' folder which reflects remote folder, however, I cannot select files from there. If it is bug in this app, it should be fixed, but even then, installing separate app instead of just entering your SFTP/SSH credentials is way more complex.

Thank you very much for opening up this issue! I am currently a bit overwhelmed by the many requests that arrive each week, so please forgive me, if I fail to respond personally. I am still very likely to at least skim read your request and I'll probably try to fix all (real) bugs if possible and I will likely review every single PR being made (please, give me a heads up if you intent to do so) and I will try to work on popular requests (please upvote via thumbs up on the original issue) whenever possible, but trying to respond to every single issue over the last years has been kind of draining and I need to adjust my approach for this project to remain fun for me and to make any progress with actually coding new stuff. Thanks for your understanding!
