Description

This may be handy when working with containers or in test environments when starting more than 1 node per host.

Suggestion is to introduce Ignite system property IGNITE_NODES_PER_HOST which is 1 by default and calculate all resource related config parameters using this value, e.g. offheap memory, pool threads, nio workers in TcpCommunicationSpi, etc. dividing total amount of available resource by IGNITE_NODES_PER_HOST.

Upd: Another suggestion is to have IGNITE_AVAILABLE_CPU property which is more intuitive.
