feat(metrics): make built-in summary objectives configurable

Add pitaya.metrics.prometheus.objectives to tune the quantiles emitted by
the built-in handler_response_time_ns and handler_handler_delay_ns
summaries, which were hard-coded to {0.7, 0.95, 0.99}. Operators can drop
unused percentiles (or emit none) to cut Prometheus series cardinality.

The map is keyed by the quantile string for YAML/env friendliness and
converted to map[float64]float64 when building SummaryOpts. The option is
intentionally not seeded with a viper default: a seeded default would be
deep-merged back into any partial override, so dropping a percentile via
config would silently fail. Unset resolves to nil, which the reporter maps
to the historical {0.7, 0.95, 0.99}, keeping default behavior identical.
