Split callees and the rate among load generators; sample every one; count K8s restarts from pods - #29

SIPp's -rate_increase takes only integers, so 50 over 8 instances (6.25) kept every uac from starting. Shares are now whole numbers that add up to the rate; a start below the instance count is rejected by the config.
…pler gaps A tick where the Metrics API had no usage gave no sample line, and a missing sample counted as a restart: the K8s soak of the full run reported 29 restarts with none in the pods' counters. On the cluster only a counter rise, or a replaced pod, is a restart. Server benchmarks count as before.
The callees were one SIPp process on the first load generator, answering every call, and it capped RoutrOne at about 2,900 calls/s however many uac instances there were. A benchmark with a register now runs as many callee processes as load.instances, each registering its share of the users (round robin) from its own port and address, spread over the load generators like the uac. Every share must register before the ramp starts, or the benchmark aborts with the callee that fell short. Saturation is judged on every callee process.
The sampler (processes and UDP counters) now runs on each worker too, and a step is invalid when a SIPp process on any load generator is over 80% of its core or any of them drops UDP packets. The report's run.infra.loadgen.count lists the droplets. The page now ignores fields of live.json it does not know, so a newer perfkit's snapshot still shows, and the version moves to 0.1.13 so browsers do not keep the old app.js.
