Introduce option to detect and fail on path overriding in rule definitions

[nicdard]

Issue #22

Description of changes:

Detect and fail in case of path overriding in rule definition which causes the undefined behavior as described in issue #22. Note that in case of OR explicit operators we do not need to fail, as the resulting patterns are being copied and therefore not overridden.

• Tests are added to JsonRuleCompiler as well asRuleCompiler.
• The GenericMachine class and related builder has been modified to be configured.
  • By default, the previous behavior is maintained, where the override is happening to avoid breaking compatibility.
• No breaking changes are introduced.
