v0.9.1

Use default implementation for input-output dependencies (#274)

WireDependencies has quite a but of subtlety at this point. It needs to
account for flowing computedness and secretness between inputs and
outputs, each of which can be handled either together or separately.
When this provider was implemented, the default implementation didn't
work as expected, and didn't cover cases such as pass through inputs.

The pulumi-go-provider now does a much better job by default, so we can
rely on that implementation. We expect the following semantics:
- If any input is computed, then all outputs are computed.
- This does not apply to an output `k` if: - There is an input also
called `k` and `k` is not computed. - `input[k] == output[k]`.
- If any input is secret, then the matching output of the same name is
also secret.


This should fix (not closing)

I'll close https://github.com/pulumi/pulumi-command/issues/256 once I
merge the examples revert.
