Fix SOnarQube bug on Regex
- Regex included unlimitted repetition is now limited to 99 99 nested yang container should sufice, in my experience in 5G 20-30 levels is the max I have seen we can always record it as a 'known limitation' -tried to improve the redability of the Regex using constant names - Added edge-case senarios testing related to query regex Issue-ID: CPS-89 Signed-off-by: ToineSiebelink <toine.siebelink@est.tech> Change-Id: Ic3442bc8ca22fe66976948f9913e033245a0e41c
