------------------------------------------

We can add startSize alongside with size method and make memory regions expandable.

> h2. 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.
> h2. Acceptance Criteria
> # Default MemoryPolicy is created with size of 80% of physical memory available on machine.
> # 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.
