finatra-jackson: added @Pattern annotation for regex based string validation

Problem

We should able to validate http request parameters whether match the given regex pattern. For instance, Finatra should able to validate phone parameter whether matches to phone pattern.

case class MyRequest(phone: String)

Solution

Added @Patternannotation to finatra-jackson for regex based validation. If the regex do not match, it will return PatternNotMatches errorCode which contains the regex and value

Result With @Pattern annotation we provide regex that checks the parameter match or not.

case class MyRequest( @Pattern(regexp= "^[+][(]{0,1}[0-9]{1,4}[)]{0,1}[-\s./0-9]$") phone: String)
