The FileParameterProvider maps a directory to a parameter group named after the directory, and the files
The KubernetesSecretParameterProvider maps a directory to a parameter group named after the directory, and the files
within the directory to parameters. Each file's name is mapped to a parameter, and the content of the file
becomes the value. Hidden files and nested directories are ignored.

While this provider can be useful in a range of cases, it particularly matches the mounted volume secret
structure in Kubernetes. A full discussion of Kubernetes secrets is beyond the scope of this document,
but a brief overview can illustrate how these secrets can be mapped to parameter groups.

Therefore, to map this secret to a parameter group that will populate a Parameter Context named 'system-credentials',
you should simply provide the following configuration to the FileParameterProvider:
