BigDecimal equality with different scale

Issue Description:

In Ansible Integration, 1.0 and 1.00 are not equal.

ListContainsExpression uses org.drools.ansible.rulebook.integration.api.domain.constraints.Operators.areNumericEqual

EqualsExpression uses org.drools.model.Index.areNumericEqual

Acceptance Criteria:

BigDecimal("1.0") and BigDecimal("1.00") are consider as equal in ansible-integration tests.
