Update provider parameter in sample json files

In the sample json files, some examples of the provider value were
wrong and showed a key manager class instead of an encryptor name.
Other samples showed the legacy encryptor classes where the newer
os-brick encryptor shorthand names should be used instead.
I3eec91e221692177833909e0378116cea4966807 removes support for the
legacy provider class names, so it is important that the samples
reflect the updated shorthand names.
