Description

Notes

Currently when user doesn't specify any MemoryPolicy configuration a default one is created. It has a fixed size of 1 GB which seems to be too rigid.
Also when user wants to override size of the default MemoryPolicy, the full syntax of this configuration must be used; it is cumbersome in such simple case.

Acceptance Criteria

1. Default MemoryPolicy is created with size of 80% of physical memory available on machine.
2. New configuration property defaultMemoryPolicySize is introduced in memoryConfiguration section to allow user to specify exact size in bytes without applying verbose syntax of memoryPolicyConfiguration section.
