Fixed issues for MiNiFi C++ agent

Summary of fixed issues for this release.

Fixed issues in this release include:
  • Fixed a bug in ExtractText where "Include Capture Group 0" was interpreted as the reverse of the boolean value. Switched to the correct interpretation, i.e. true became false and false became true.
  • Fixed a bug in InvokeHTTP which made it try to send all flow file attributes as headers when "Attributes to Send" was empty or not set (introduced in 1.21.10).
  • An issue which made ListenSyslog always fail validation in EFM (introduced in 1.22.04).
  • Various issues with CRON_DRIVEN scheduling, making it ready for production use.
