Merge 4233a7c292 into 984c38e03e

## Changes
Integration tests using these fixtures could have been flaky when run in
parallel using the same user's identity. They would also possibly have
piggybacked state from previous runs.

This PR adds a UUID to the root_path to force independent bundle
deployments for every test run.

I have checked that all bundles in `internal/bundle/bundles` have
`root_path` namespaced to a UUID.

## Tests
Self testing.

 # Version changelog
 
+## [Release] Release v0.235.0
+
+**Note:** the `bundle generate` command now uses the `.<resource-type>.yml`
+sub-extension for the configuration files it writes. Existing configuration
+files that do not use this sub-extension are renamed to include it.
+
+Bundles:
+ * Make `TableName` field part of quality monitor schema ([#1903](https://github.com/databricks/cli/pull/1903)).
+ * Do not prepend paths starting with ~ or variable reference ([#1905](https://github.com/databricks/cli/pull/1905)).
+ * Fix workspace extensions filer accidentally reading notebooks ([#1891](https://github.com/databricks/cli/pull/1891)).
+ * Fix template initialization when running on Databricks ([#1912](https://github.com/databricks/cli/pull/1912)).
+ * Source-linked deployments for bundles in the workspace ([#1884](https://github.com/databricks/cli/pull/1884)).
+ * Added integration test to deploy bundle to /Shared root path ([#1914](https://github.com/databricks/cli/pull/1914)).
+ * Update filenames used by bundle generate to use `.<resource-type>.yml` ([#1901](https://github.com/databricks/cli/pull/1901)).
+
+Internal:
+ * Extract functionality to detect if the CLI is running on DBR ([#1889](https://github.com/databricks/cli/pull/1889)).
+ * Consolidate test helpers for `io/fs` ([#1906](https://github.com/databricks/cli/pull/1906)).
+ * Use `fs.FS` interface to read template ([#1910](https://github.com/databricks/cli/pull/1910)).
+ * Use `filer.Filer` to write template instantiation ([#1911](https://github.com/databricks/cli/pull/1911)).
