Upgrade CI (typedb#67)

## What is the goal of this PR?

We bring the CI pipeline in to line with the other Grakn repos, and enable creating end-to-end and integration tests that can depend upon a specific Grakn commit.

## What are the changes implemented in this PR?

- Updates to Bazel 0.25.2
- Swaps `force_python` for `python_version` as per new Bazel 
- Updates pip deployment for `snapshot` and `release`
- Overhauls WORKSPACE file, and includes the necessary transitive dependencies
