* fixesopenziti/ziti#4094 accept first-party certs issued by a separate edge signing CA
- adds FirstPartyX509CertValidation and ThirdPartyX509CertValidation usages and an
intermediates field to the router data model public keys, deprecating
ClientX509CertValidation
- publishes config CA bundle roots as first-party anchors with their intermediates and
Ca store entries as third-party anchors; controller certs carry JWT validation only,
since a controller identity is never a CA and anchors no client cert chains
- builds router first-party and client cert trust pools from the published usages,
falling back to the deprecated usage against older controllers
- propagates the full signing cert chain between controllers via a new mesh
SigningCertChainHeader and persists whole chains in controller records
- removes the orphaned InstantStrategy.AddPublicKey, dead since public key sync moved
to controller list data
- gives each command dispatcher its own decoder registry so multiple in-process
controllers no longer decode into the last-started controller's managers
- adds a three-controller in-process HA test harness with a split signing PKI,
cluster formation and first-party cert integration tests
- trusts the edge signing CA when verifying router control channel certs
- adds a variadic additionalRoots parameter to VerifyLeafCertChain, applied to a
clone of the caller's pool so an identity's live tls.Configs are unaffected
- passes the edge enrollment signing CA bundle as additional roots when admitting
a router control channel connection, so a deployment whose signing CA sits
outside the controller's own trust bundle no longer has every router refused
- leaves the fingerprint check bound to the verified leaf, so the wider anchor set
changes which chains verify, not which routers are admitted
- covers the split-root case and the caller-pool guarantee in common/cert tests
- adds a common/servermetrics package that owns the metrics MetricsMessage wire
format and the reporting/usage subsystem (message builder, usage registry,
interval and usage counters), wrapping the openziti/metrics Registry for
metric collection
- moves the controllers metrics reporter into the router package and removes it
from the shared metrics package, breaking a common -> router/env import cycle
- repoints controller and router consumers to common/servermetrics; base metric
collection stays on openziti/metrics
- keeps the proto field numbers and the metrics content-type identical so the
encoding is byte-compatible across the move, and uses a distinct proto package
name so ziti's and the library's messages coexist without a global proto
registry clash
- adds a round-trip test asserting wire compatibility with the library's
MetricsMessage
- leaves openziti/metrics unchanged, so sdk-golang and the shared xgress data
plane are unaffected
