Description

This story aims to improve stack trace resolving in JsonTemplateLayout from

config      = field , [ stringified ]
field       = "field" -> (
                "className"
              | "message"
              | "stackTrace"
              )
stringified = "stringified" -> boolean

to

config              = field , [ stringified ] , [ stackTrace ]
field               = "field" -> ( "className" | "message" | "stackTrace" )

stackTrace          = "stackTrace" -> stringified
stringified         = "stringified" -> ( boolean | truncation )
truncation          = "truncation" -> (
                        [ suffix ]
                      , [ pointMatcherStrings ]
                      , [ pointMatcherRegexes ]
                      )
suffix              = "suffix" -> string
pointMatcherStrings = "pointMatcherStrings" -> string[]
pointMatcherRegexes = "pointMatcherRegexes" -> string[]
