## Changes
This is one step (of many) toward moving the integration tests around.
This change consolidates the following functions:
* `ReadFile` / `WriteFile`
* `GetEnvOrSkipTest`
* `RandomName`
## Tests
n/a
## Changes
These tests allow us to get information for execution context
(PYTHONPATH, CWD) for various Python tasks and different cluster setups.
Note: this test won't be executed automatically as part of nightly
builds since it requires RUN_PYTHON_TASKS_TEST env to be executed.
## Tests
Integration test run successfully.
