Move integration tests to `integration` package (#2009)

## Changes

Objectives:
* A dedicated directory for integration tests
* It is not picked up by `go test ./...`
* No need for a `TestAcc` test name prefix
* More granular packages to improve test selection (future)

The tree structure generally mirrors the source code tree structure.

Requirements for new files in this directory:
* Every package **must** be named after its directory with `_test` appended
* Requiring a different package name for integration tests avoids
aliasing with the main package.
* Every integration test package **must** include a `main_test.go` file.

These requirements are enforced by a unit test in the `integration` package.

## Tests

Integration tests pass.

The total run time regresses by about 10%. A follow-up change that
increases the degree of test parallelism will address this.

+# Integration tests
+
+This directory contains integration tests for the project.
+
+The tree structure generally mirrors the source code tree structure.
+
+Requirements for new files in this directory:
+* Every package **must** be named after its directory with `_test` appended
+  * Requiring a different package name for integration tests avoids aliasing with the main package.
+* Every integration test package **must** include a `main_test.go` file.
+
+These requirements are enforced by a unit test in this directory.
+
+## Running integration tests
+
+Integration tests require the following environment variables:
+* `CLOUD_ENV` - set to the cloud environment to use (e.g. `aws`, `azure`, `gcp`)
+* `DATABRICKS_HOST` - set to the Databricks workspace to use
+* `DATABRICKS_TOKEN` - set to the Databricks token to use
+
+Optional environment variables:
+* `TEST_DEFAULT_WAREHOUSE_ID` - set to the default warehouse ID to use
+* `TEST_METASTORE_ID` - set to the metastore ID to use
+* `TEST_INSTANCE_POOL_ID` - set to the instance pool ID to use
+* `TEST_BRICKS_CLUSTER_ID` - set to the cluster ID to use
+
+To run all integration tests, use the following command:
+
+```bash
+go test ./integration/...
+```
+
+Alternatively:
+
+```bash
+make integration
+```
