Support Incremental xDS mode (#9855) This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged. Union of all commit messages follows to give an overarching summary: xds: exclusively support incremental xDS when using xDS v3 Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail. Work around a strange older envoy behavior involving empty CDS responses over incremental xDS. xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead. Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client. xds: pull out checkStreamACLs method in advance of a later commit xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty. This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10. xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time

xds: fix representation of incremental xDS subscriptions (#10987) Fixes #10563 The `resourceVersion` map was doing two jobs prior to this PR. The first job was to track what version of every resource we know envoy currently has. The second was to track subscriptions to those resources (by way of the empty string for a version). This mostly works out fine, but occasionally leads to consul removing a resource and accidentally (effectively) unsubscribing at the same time. The fix separates these two jobs. When all of the resources for a subscription are removed we continue to track the subscription until envoy explicitly unsubscribes

xds: fix representation of incremental xDS subscriptions (#10987) Fixes #10563 The `resourceVersion` map was doing two jobs prior to this PR. The first job was to track what version of every resource we know envoy currently has. The second was to track subscriptions to those resources (by way of the empty string for a version). This mostly works out fine, but occasionally leads to consul removing a resource and accidentally (effectively) unsubscribing at the same time. The fix separates these two jobs. When all of the resources for a subscription are removed we continue to track the subscription until envoy explicitly unsubscribes

Support Incremental xDS mode (#9855) This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged. Union of all commit messages follows to give an overarching summary: xds: exclusively support incremental xDS when using xDS v3 Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail. Work around a strange older envoy behavior involving empty CDS responses over incremental xDS. xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead. Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client. xds: pull out checkStreamACLs method in advance of a later commit xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty. This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10. xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time

xds: fix representation of incremental xDS subscriptions (#10987) Fixes #10563 The `resourceVersion` map was doing two jobs prior to this PR. The first job was to track what version of every resource we know envoy currently has. The second was to track subscriptions to those resources (by way of the empty string for a version). This mostly works out fine, but occasionally leads to consul removing a resource and accidentally (effectively) unsubscribing at the same time. The fix separates these two jobs. When all of the resources for a subscription are removed we continue to track the subscription until envoy explicitly unsubscribes

Support Incremental xDS mode (#9855) This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged. Union of all commit messages follows to give an overarching summary: xds: exclusively support incremental xDS when using xDS v3 Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail. Work around a strange older envoy behavior involving empty CDS responses over incremental xDS. xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead. Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client. xds: pull out checkStreamACLs method in advance of a later commit xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty. This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10. xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time
