Description
Sometimes during test generation UTBot fails with OutOfMemoryError exception (see comment ). Currently UTBot subprocess starts with default memory settings and user cannot change it to resolve such problem.

Expected behavior
There is setting .utbot\settings.properties file to change memory allocation settings. For now it seems to be a rare problem, so I think we should not expose it to IDEA settings UI.

Potential alternatives
Dynamically decide how much memory to use based on available memory. But that seems more error-prone solution and may not resolve such problem.
