Commit Message

[integration-test] Reserve service ports across restarts to fix port races (#728)

- Bug fix
- Improvement (improvement to code, performance, etc)

- Allocate each service's gRPC/HTTP ports directly into the process that
owns them, holding a listener on each from allocation until the
subprocess
binds it, and re-reserving the moment the subprocess stops (`Stop`) so a
parallel test cannot claim a just-freed port while the service is down.
- Drop the central reservation pool and the allocate-then-transfer
machinery
(`claim`/`claimAll`/`closeAll`); defer config-file writing to a second
pass
once every service endpoint is known, since a template renders the whole
  `SystemConfig`.
- Pre-allocate the load generators in `NewRuntime` like the other
services:
the primary reserves its ports, while the distributed client binds its
own
ephemeral port (nothing dials it). Their config is rendered in
`startLoadGen`,
  where the template and worker count are known from the service flags.
- Add `OrdererEnv.ReserveListeners`/`ReleaseListeners` so the orderer
test
  environment follows the same stop-then-reserve pattern.

- resolves #696

- resolves #738
