Sometimes workloads could come with unspecified protocols such as when running on Kubernetes. Currently, if this is the case, we will just default to tcp protocol.
However, to make sidecar-proxy controller work with l7 protocols we should instead inherit the protocol from service. This change adds tracking for services that a workload is part of and attempts to inherit the protocol whenever services a workload is part of doesn't have conflicting protocols.
This change builds on #19043 and #19067 and updates the sidecar controller to use those computed resources. This achieves several benefits:
* The cache is now simplified which helps us solve for previous bugs (such as multiple Upstreams/Destinations targeting the same service would overwrite each other)
* We no longer need proxy config cache
* We no longer need to do merging of proxy configs as part of the controller logic
* Controller watches are simplified because we no longer need to have complex mapping using cache and can instead use the simple ReplaceType mapper.
It also makes several other improvements/refactors:
* Unifies all caches into one. This is because originally the caches were more independent, however, now that they need to interact with each other it made sense to unify them where sidecar proxy controller uses one cache with 3 bimappers
* Unifies cache and mappers. Mapper already needed all caches anyway and so it made sense to make the cache do the mapping also now that the cache is unified.
* Gets rid of service endpoints watches. This was needed to get updates in a case when service's identities have changed and we need to update proxy state template's spiffe IDs for those destinations. This will however generate a lot of reconcile requests for this controller as service endpoints objects can change a lot because they contain workload's health status. This is solved by adding a status to the service object tracking "bound identities" and have service endpoints controller update it. Having service's status updated allows us to get updates in the sidecar proxy controller because it's already watching service objects
* Add a watch for workloads. We need it so that we get updates if workload's ports change. This also ensures that we update cached identities in case workload's identity changes.
This commit adds a new type ComputedDestinations that will contain all destinations from any Destinations resources and will be name-aligned with a workload. This also adds an explicit-destinations controller that computes these resources.
This is needed to simplify the tracking we need to do currently in the sidecar-proxy controller and makes it easier to query all explicit destinations that apply to a workload.
We serially attempt to decode resources in the consul resource apply command
using HCL and then falling back on JSON. This causes the HCL errors to be
dropped completely in the case where the HCL decode failed due to a typo
instead of it actually being JSON instead.
This PR proposes sniffing to see if the first non-whitespace character in the
input is { and if so treat it as JSON, otherwise as HCL and not
double-decode on error.
When the v2 catalog experiment is enabled the old v1 catalog apis will be
forcibly disabled at both the API (json) layer and the RPC (msgpack) layer.
This will also disable anti-entropy as it uses the v1 api.
This includes all of /v1/catalog/*, /v1/health/*, most of /v1/agent/*,
/v1/config/*, and most of /v1/internal/*.
* Introduce a new type `ComputedProxyConfiguration` and add a controller for it. This is needed for two reasons. The first one is that external integrations like kubernetes may need to read the fully computed and sorted proxy configuration per workload. The second reasons is that it makes sidecar-proxy controller logic quite a bit simpler as it no longer needs to do this.
* Generalize workload selection mapper and fix a bug where it would delete IDs from the tree if only one is left after a removal is done.

This PR fixes an issue where upstreams did not correctly inherit the proper
namespace / partition from the parent service when attempting to fetch the
upstream protocol due to inconsistent normalization.
Some of the merge-service-configuration logic would normalize to default, while
some of the proxycfg logic would normalize to match the parent service. Due to
this mismatch in logic, an incorrect service-defaults configuration entry would
be fetched and have its protocol applied to the upstream.
