feat: Upload projects (#1436)

`sqlc upload` will package up schema, queries and output code and upload it to sqlc Cloud. Uploaded projects are used to verify future sqlc releases; all uploaded code is tested for backwards-incompaitble changes.

* bundler: Add flag to dump request data

Add the `--dry-run` flag to see the exact HTTP request that sqlc will
make to the the upload endpoint.

* docs: Add documentation for the upload subcommand

+# Uploading projects
+
+*This feature requires signing up for [sqlc Cloud](https://app.sqlc.dev), which is currently in beta.*
+
+Uploading your project ensures that future releases of sqlc do not break your
+existing code. Similar to Rust's [crater](https://github.com/rust-lang/crater)
+project, uploaded projects are tested against development releases of sqlc to
+verify correctness.
+
+## Add configuration
+
+After creating a project, add the project ID to your sqlc configuration file.
+
+```yaml
+version: "1"
+project:
+  id: "<PROJECT-ID>"
+packages: []
+```
+
+```json
+{
+  "version": "1",
+  "project": {
+    "id": "<PROJECT-ID>"
+  },
+  "packages": [
+  ]
+}
+```
+
+You'll also need to create an API token and make it available via the
+`SQLC_AUTH_TOKEN` environment variable.
+
+```shell
+export SQLC_AUTH_TOKEN=sqlc_xxxxxxxx
+```
+
+## Dry run
+
+You can see what's included when uploading your project by using using the `--dry-run` flag:
+
+```shell
+sqlc upload --dry-run
+```
+
+The output will be the exact HTTP request sent by `sqlc`.
+
+## Upload
+
+Once you're ready to upload, remove the `--dry-run` flag.
+
+```shell
+sqlc upload
+```
+
+By uploading your project, you're making sqlc more stable and reliable. Thanks!
