Introducing Antlr4 for cpsPath parsing
-created new module for cpPathParser -added antlr rule for cpsPathWithSingleLeafCondition -added antlr rule for cpsPathWithDescendant (and with leaf conditions) -added antlr rule for ancestor axis -added unit test (copied from existing CpsPathQuerySpec) -udpated cps-ri to use new cpPathQuery from parser module -'imported' lexer rules from publix xPath grammar -Re-used existing CpsPathException but conversion happens in cps-ri to prevent additional dependency in cps-path-parser module Issue-ID: CPS-376 Change-Id: I2c5df98969402cbf69f6573c52705879450ce606 Signed-off-by: ToineSiebelink <toine.siebelink@est.tech>
