Figure out a way to hide SnapshotUpdateParameters from UpdateSnapshot and split it into two separate convenience methods: Archive and Recover

The UpdateSnapshot method needs to be hidden and split into two separate convenience methods: Archive and Recover.
These APIs need to be hand-written wrappers on top of UpdateSnapshot to hide the complexity of setting up a SnapshotUpdateParameters from the end-user:

azure-sdk-for-cpp/sdk/appconfiguration/azure-data-appconfiguration/inc/azure/data/appconfiguration/configuration_client.hpp

Lines 109 to 115 in 514c4cc

	UpdateSnapshotRequestContentType const& contentType,
	std::string const& name,
	std::string const& accept,
	SnapshotUpdateParameters const& entity,

	Core::Context const& context = {}) const;
