Upgrade to Protovalidate v0.11.0 (#291)

This upgrades to the latest v0.11.0 release of Protovalidate. As a
result, it conforms to the convention of using `rule` everywhere instead
of `constraint`. All usages of `constraint` have been removed.

In addition, this adds a few additional tests to the `expected_failures`
list as a result of v0.11.0.
