--------------------------------------------------------------------
when entry is updated, both 'invoke update' and get\put\remove metrics updated.
when entry processor is invoked, but cache entry isn't affected then invoke
metric isn't incremented.
'invoke * ' metrics incremented only when cache entry value is affected(read or
updated) by entry processor(not just when entry processor is invoked).If entry
processor is called once, and multiple entries are affected, then local invoke
metric is incremented only once, cluster global metric is incremented once.

>
> {{CacheMetrics}} object has multiple metrics for various cache operations
> like {{get}}, {{put}} and {{remove}}, but nothing for
> {{invoke}}/{{EntryProcessor}}. It makes sense to add such metrics, for
> example:
> * Total number of `invoke` operations executed.
> * Number of `invoke` operations that included updates.
> * Number of read-only `invoke` operations.
> * Min/max/avg execution time.
> * ...
