Add function to suppress parameter output of sensitive information
What does this PR do?
Fixes #706 - I believe it would be good if secret information contained in the parameters was masked with a string like ******.
Obfuscation of sensitive parameters
By applying this pull request, papermill will obfuscate the value stored in the injected-parameters cell and notebook metadata for parameters that contain strings like token and secret. I have not implemented obfuscation of these parameters in the output cell because it is not simple to do so and I assume it would have a significant impact.
For security reasons, I considered that it would be better to enable obfuscation by default. So I added the option --no-obfuscate-sensitive-parameters to turn it off.
In addition, the parameters that should be marked as sensitive are listed in papermill.utils.SENSITIVE_PARAMETER_PATTERNS. The --sensitive-parameter-patterns option can be used to customize the list.
