rgwlc: add lifecycle perf counters

rgwlc: add lifecycle perf counters

Historically, RGW lifecycle processing has not provided perfcounters.
A single expire counter was added in recent parallel lifecycle changes,
but granular counters for

    current expiration
    non-current expiration
    delete-marker expiration
    current transition
    non-current transition
    mpu aborts

are arguably much more useful, and can be summed in reports.
