Alexander Ignatov 78beeb1c0f Added option to disable sahara db for storing job binaries.
Now it's possible to disable internal-db to upload new job-binaries.
All other manipulations (GET, DELETE, PATCH) are still posible not
to break existing workloads and ability to run jobs with already
created job binary internals. Special configuration option added for
that.
