Create HostGetSupportedAssertions() and only give hosts supported assertions. #103

Closed dandclark closed 4 years ago

dandclark commented 4 years ago

Add a new host operation for hosts to specify the assertion keys that they support. Only supported assertions are returned to the host. This ensures that unsupported assertions will be handled in the same way (ignored) across all hosts.

Resolves #102.
