- 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
