## Problem
We need to test the stability of Neon.
## Summary of changes
The test runs random operations on a Neon project. It performs via the
Public API calls the following operations: `create a branch`, `delete a
branch`, `add a read-only endpoint`, `delete a read-only endpoint`,
`restore a branch to a random position in the past`. All the branches
and endpoints are loaded with `pgbench`.
