* Fix HDFS with AD auth for browse, read
- HDFS now fully supports expanding nodes for all levels, including using cookie for auth
- HDFS now support reading files from HDFS
- HDFS write file is broken and will be fixed (either in PR update or separate PR)
- Removed hack to use gateway-0 instead of actual DNS name now these are supported. Needed for testing
* Fix Jupyter error using new DMV with endpoints
Partially working AD support for BDCs with some known issues
- Plumbed through kerberos support to Notebooks.
- Using "gateway-0" for service temporarily as service endpoints API doesn't yet return correct DNS name. Will update in separate PR once available
- Plumbed kerberos auth to HDFS, Spark. Only partially working as we use same token on each call
- Will fix in separate PR, as this requires a refactor of WebHDFS library. Will need to either get new token every time or set a cookie, both of which require refactors
- Fixed error when Data Service node expansion failed and blocked all OE expansion
- Support for SqlToolsService change to use new cluster endpoints DMV
- Updated API to add new endpoints field to replace IP + port
- Added logic to handle case where endpoints for Yarn, Grafana etc. are in the list
- Sort list and use expected new localized strings
- Updated SqlToolsService to include support for new DMV
- Add "gateway-0" handling in Jupyter session as workaround for lack of domain names in endpoints list
Adds a protocol handler for notebook open, which can be used from browsers
Uses extension-based handler support so all URIs must start with `azuredatastudio://microsoft.notebook`
Adds 2 actions:
- `/new` opens a new empty notebook
- `/open` opens a HTTP/S file as an untitled notebook or text document
Sample URL:
```
azuredatastudio://microsoft.notebook/open?url=https%3A%2F%2Fraw.githubusercontent.com%2Fkevcunnane%2Fmsbuild_ads_demo%2Fmaster%2F0_YoAzdata.ipynb
```
