Add support for IBM Cloud

[x4v13r64]

The python SDK looks pretty mature:

• https://pypi.org/project/watson-developer-cloud/
• https://github.com/watson-developer-cloud/python-sdk The above aren't for IBM cloud per se, but rather Watson.

There's a library for the COS service (similar to S3):

• https://ibm.github.io/ibm-cos-sdk-python/
• https://github.com/IBM/ibm-cos-sdk-python
• https://medium.com/ibm-data-science-experience/working-with-ibm-cloud-object-storage-in-python-fe0ba8667d5f

Other then that it looks like the API has to be called directly, e.g. https://github.com/IBM/ibm-cloud-functions-serverless-apis.

Could add some basic support.
