During peer stream replication we flatten checks from the source cluster and build one thin overall check to hide the irrelevant details from the consuming cluster. This flattening logic did correctly flip to non-passing if there were any non-passing checks, but WHICH status it got during that was random (warn/error).
Also it didn't represent "maintenance" operations. There is an api package call AggregatedStatus which more correctly flattened check statuses.
This PR replicated the more complete logic into the peer stream package.
This commit adds handling so that the replication stream considers
whether the user intends to peer through mesh gateways.
The subscription will return server or mesh gateway addresses depending
on the mesh configuration setting. These watches can be updated at
runtime by modifying the mesh config entry.
newMockSnapshotHandler has an assertion on t.Cleanup which gets called before the event publisher is cancelled. This commit reorders the context.WithCancel so it properly gets cancelled before the assertion is made.
This mimics xDS's discovery protocol where you must request a resource
explicitly for the exporting side to send those events to you.
As part of this I aligned the overall ResourceURL with the TypeURL that
gets embedded into the encoded protobuf Any construct. The
CheckServiceNodes is now wrapped in a better named "ExportedService"
struct now.
Previously, public referred to gRPC services that are both exposed on
the dedicated gRPC port and have their definitions in the proto-public
directory (so were considered usable by 3rd parties). Whereas private
referred to services on the multiplexed server port that are only usable
by agents and other servers.
Now, we're splitting these definitions, such that external/internal
refers to the port and public/private refers to whether they can be used
by 3rd parties.
This is necessary because the peering replication API needs to be
exposed on the dedicated port, but is not (yet) suitable for use by 3rd
parties.
