We adopt a new algoritm for annotating secrets, which works as
follows:
If the source and destinations are both property maps, annotate their
secrets deeply.
Otherwise, if there is an property in both the input and output arrays
with the same name and the value in the inputs has secrets /anywhere/
in it, mark the output itself a secret.
This means, for example, an array in the inputs with a secret value as
one of the elmenets will mean in the outputs the entire array value is
marked as a secret. This is done because arrays often are treated as
sets by providers and so we really shouldn't consider ordering. It
also means that if a value is added to the array as part of the
operation we still mark the new array as an output even though the
values may not be indentical to the inputs.
