…ine (#6728) (#13132)

* feat: add google_vertex_ai_index for Vertex AI Matching Engine

* fix: increase timeouts to 60 min because 20 wasn't enough for creation

* fix: change coe to make name computed instead of an input

* fix: use costom flatten code to ignore_read a nested property's field

* fix: add skip_import_test: true to the auto-gen test

* feat: add a test with a manually updated ImportStateVerifyIgnore

* Apply suggestions from code review [ci skip]

Update descriptions based on the suggestions

* refactor: use ignore_read_extra instead of a manual test

* fix: use an empty object for bruteForceConfig

* feat: define additional fields to api.yaml

* feat: add an example to increase test coverage

* feat: deal with contentsDeltaUri as an updatable field

* fix: fix the error because the cosine distance type only supports unit l2 norm type

This is the error message from the endpoint:
"Index with `COSINE_DISTANCE` distanceMeasureType currently only supports `UNIT_L2_NORM` featureNormType."

* feat: remove approximate_neighbors_count from an example with brute_force_config

approximate_neighbors_count is required if tree-AH algorithm is used.

* test: add a handwritten test for patch

* fix: add update_mask: true to use the mask as a url param

* refactor: put 'input: true' on the fields patch couldn't update

* feat: use custom pre update code for a nested object

* fix: update the handwritten test accordingly

* feat: add custom flatten code for is_complete_overwrite
