## Changes
This change moves fixture helpers to `internal/acc/fixtures.go`. These
helpers create an ephemeral path or resource for the duration of a test.
Call sites are updated to use `acc.WorkspaceTest()` to construct a
workspace-focused test wrapper as needed.
This change also moves the `GetNodeTypeID()` function to `testutil`.

## Changes
Using an interface instead of a concrete type means we can pass
`*testing.T` directly or any wrapper type that implements a superset of
this interface. It prepares for more broad use of `acc.WorkspaceT`,
which enhances the testing object with helper functions for using a
Databricks workspace.
This eliminates the need to dereference a `*testing.T` field on a
wrapper type.
## Tests
n/a
## Changes
Validation rules on tags are different per cloud (they are passed
through to the underlying clusters and as such must comply with
cloud-specific validation rules). This change adds tests to confirm the
current behavior to ensure the normalization we can apply is in line
with how the backend behaves.
## Tests
The new integration tests pass (tested locally).
