* [Cloud][CC-6925] Updates to pushing server state (#19682)
* Upgrade hcp-sdk-go to latest version v0.73
Changes:
- go get github.com/hashicorp/hcp-sdk-go
- go mod tidy
* From upgrade: regenerate protobufs for upgrade from 1.30 to 1.31
Ran: `make proto`
Slack: https://hashicorp.slack.com/archives/C0253EQ5B40/p1701105418579429
* From upgrade: fix mock interface implementation
After upgrading, there is the following compile error:
cannot use &mockHCPCfg{} (value of type *mockHCPCfg) as "github.com/hashicorp/hcp-sdk-go/config".HCPConfig value in return statement: *mockHCPCfg does not implement "github.com/hashicorp/hcp-sdk-go/config".HCPConfig (missing method Logout)
Solution: update the mock to have the missing Logout method
* From upgrade: Lint: remove usage of deprecated req.ServerState.TLS
Due to upgrade, linting is erroring due to usage of a newly deprecated field
22:47:56 [consul]: make lint
--> Running golangci-lint (.)
agent/hcp/testing.go:157:24: SA1019: req.ServerState.TLS is deprecated: use server_tls.internal_rpc instead. (staticcheck)

* From upgrade: adjust oidc error message
From the upgrade, this test started failing:
=== FAIL: internal/go-sso/oidcauth TestOIDC_ClaimsFromAuthCode/failed_code_exchange (re-run 2) (0.01s)
oidc_test.go:393: unexpected error: Provider login failed: Error exchanging oidc code: oauth2: "invalid_grant" "unexpected auth code"
Prior to the upgrade, the error returned was:
```
Provider login failed: Error exchanging oidc code: oauth2: cannot fetch token: 401 Unauthorized\nResponse: {\"error\":\"invalid_grant\",\"error_description\":\"unexpected auth code\"}\n
```
Now the error returned is as below and does not contain "cannot fetch token"
```
Provider login failed: Error exchanging oidc code: oauth2: "invalid_grant" "unexpected auth code"
```
* Update AgentPushServerState structs with new fields
HCP-side changes for the new fields are in:
https://github.com/hashicorp/cloud-global-network-manager-service/pull/1195/files
* Minor refactor for hcpServerStatus to abstract tlsInfo into struct
This will make it easier to set the same tls-info information to both
- status.TLS (deprecated field)
- status.ServerTLSMetadata (new field to use instead)
* Update hcpServerStatus to parse out information for new fields
Changes:
- Improve error message and handling (encountered some issues and was confused)
- Set new field TLSInfo.CertIssuer
- Collect certificate authority metadata and set on TLSInfo.CertificateAuthorities
- Set TLSInfo on both server.TLS and server.ServerTLSMetadata.InternalRPC
* Update serverStatusToHCP to convert new fields to GNM rpc
* Add changelog
* Feedback: connect.ParseCert, caCerts
* Feedback: refactor and unit test server status
* Feedback: test to use expected struct
* Feedback: certificate with intermediate
* Feedback: catch no leaf, remove expectedErr
* Feedback: update todos with jira ticket
* Feedback: mock tlsConfigurator
* make proto for additional file in 1.17 not in main
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.
