DB Locking issues in BorgJob

[m3nu]

Fixes #1081

Its ok for me, I was thinking about the same location to put a lock. I was afraid you wanted to lock all the job.
Yes I added a lock on keyring because there was a deadlock and I didn't know why.

Notice that with an api for the database, we could control access to the db easier and so add lock easier.

Which API is that? You mean wrapping Peewee and doing locking there?

But thanks for checking. Will merge it then.

Oh I mentioned the module pattern in which you have the api folder.

Ah, I see db_ro, db_rw.
