common: ceph::perf_counters::make_cache_key()

a flat representation of a set of prometheus labels, returned as a
std::string. this string can either be used for sorting an ordered
container of perf counters, or for hashing an unordered container

use a variadic template to initialize a temporary array for sorting

use rvalue-ref to c array instead of variadic template
