Subject: [PATCH] visor: register RuntimeLogs on the RPC server
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The hypervisor UI's "view logs" action and 'cli visor logs' both
hit Visor.RuntimeLogs() through the RPC client, but the RPC server
type (*RPC) had no RuntimeLogs method registered. Stock net/rpc
exposes only methods on the registered receiver via reflection, so
client calls came back with

  Rpc: can't find method app-visor.RuntimeLogs.

API.RuntimeLogs, Visor.RuntimeLogs, and the rpcClient.RuntimeLogs
client wrapper were already in place — the dispatcher in
pkg/visor/rpc_visor.go was the missing piece. Add it next to
GetRuntimeConfig (same shape: zero-arg in, *string out).
