> Summarize discussions:
> Add log message in case partitions distribution is not close to even
> distribution:
> # Add system property IGNITE_PART_DISTRIBUTION_WARN_THRESHOLD with default
> value 0.1 to print warn message only when nodes count differs more then
> threshold;
> # The statistic is calculated and printed only for the local node;
> # Statistic is placed at the {{GridAffinityAssignmentCache#calculate}} and
> calculated for new {{idealAssignment}}.
> # Message format is
> {noformat}
> Local node affinity assignment distribution is not ideal [cache=,
> expectedPrimary=,
> exectedBackups=,
> primary=, backups=].
> {noformat}
> e.g. for cache with name "test", 2 backups, 4 partition, 3 nodes:
> {noformat}
> Local node affinity assignment distribution is not ideal [cache=test,
> expectedPrimary=1.33 (33.3%), exectedBackups=2.66 (66.66%), primary=1 (25%),
> backups=3(75%)].
> {noformat}
