Jupyter-enterprise-gateway

Jupyter Enterprise Gateway release 2.1.1 is strictly a maintenance release:

- jupyter_client's cache_ports feature is disabled since they don't apply to remote kernels
- KeyError: 'jinja2_env' when the kernel doesn't exist no longer occurs
- pycrypto has been replaced with pycryptodomex
- Python kernel launcher was made compatible with Python 2
- Tolerate async updates coming on next notebook release. This allows this EG release to continue working with updated Notebook releases until EG 2.2 is ready.

**Many thanks to the following contributors:**
- Alan Chin (akchinSTC)
- Blair Azzopardi (bsdz)
- Kevin Bates (kevin-bates)
- Luciano Resende (lresende)

Jupyter Enterprise Gateway release 2.1.0 includes the following:

- Enterprise Gateway is no longer dependent on Jupyter Kernel Gateway - allowing for increased freedom to make handler-based changes
- [Dynamic Configurables](https://jupyter-enterprise-gateway.readthedocs.io/en/latest/config-options.html#dynamic-configurables) are now available
- EG now uses [yarn-api-client 1.x](https://github.com/CODAIT/hadoop-yarn-api-python-client/releases) for its interactions with Hadoop YARN cluster managers
- Enhancements towards better HA support
- Documentation updates
- Bug fixes
