lib/tenantmetrics: improves CounterMap performance with large numbers of tenants 
Previously, map for storing tenant metrics was re-created to each newly ingested tenant. It has significant performance impact for systems with large number of tenants.

 This commit addresses this issue by changing algorithm of creating tenant metric records at map. Instead of map re-creation, it uses `sync.Map` primitive.

Benchmark results:
