## Changes
This helper:
* Constructs a context
* Constructs a `*databricks.WorkspaceClient`
* Ensures required environment variables are present to run an
integration test
* Enables debugging integration tests from VS Code
Debugging integration tests (from VS Code) is made possible by a prelude
in the helper that checks if the calling process is a debug binary, and
if so, sources environment variables from
`~/..databricks/debug-env.json` (if present).
## Tests
Integration tests still pass.

## Changes
A bug in the code that pulls the remote state could cause the local
state to be empty instead of a copy of the remote state. This happened
only if the local state was present and stale when compared to the
remote version.
We correctly checked for the state serial to see if the local state had
to be replaced but didn't seek back on the remote state before writing
it out. Because the staleness check would read the remote state in full,
copying from the same reader would immediately yield an EOF.
## Tests
* Unit tests for state pull and push mutators that rely on a mocked
filer.
* An integration test that deploys the same bundle from multiple paths,
triggering the staleness logic.
Both failed prior to the fix and now pass.
