Make stable release more stable together with FEDOT

Even if integration tests pass in GOLEM, after updating `stable` branch FEDOT's integration tests on `master` could fail.

How to check it? How to automate it?

Sketch of a possible scenario, somewhat elaborated:

1. Maybe make `develop` branch in GOLEM that will be `pre-stable` in a sense.
2. Make `develop` branch in FEDOT, that will depend on GOLEM `develop` branch.
- It will be automatically bumped whenever GOLEM `develop` updates;
- It will automatically run integration tests
- If integration tests pass, then *automatically* `stable` in FEDOT is bumped to `develop` version
