Validate conformance.mappingtable.pattern for out of range numbers

## Problem
Currently conformance.mappingtable.pattern is not validated and when the user inputs a number there that is out of range, for example instead of {1} he puts {-1} it outputs `Exception in thread "main" java.lang.IllegalArgumentException: negative argument number: -1` and in case of {12} the file name turn into jibberish `Exception in thread "main" org.apache.spark.sql.AnalysisException: Path does not exist: hdfs://localhost:8020/maps/ConformanceRulesMultiKey/latest-%7B4%7D;`

## Feature
Validate that the numbers in conformance .mappingtable.pattern property are in some range that is usable and do it as soon as possible.
