Fixed issues for MiNiFi C++ agent

Summary of fixed issues for the latest release.

Fixed issues in CEM MiNiFi C++ Agent - 1.23.02:

• Fixed a crash after C2 property updates.
• Fixed a bug where the old flow was not restarted after a failed C2 flow update (publish).
• Fixed a crash when empty flow files were read from python scripted processors.
• Fixed a 1 byte leak on each SID lookup in ConsumeWindowsEventLog.
• Fixed scheduling to retry after the yield period even if the processor trigger fails, and it would otherwise not be scheduled again (for example: cron daily).
• Fixed a bug in ConsumeWindowsEventLog that caused output flow file attributes containing resolved identifiers to be missing when using JSON output format.
• Fixed a bug that caused the flow file repository to keep growing with invalid entries if the flow file checkpoint is not empty, after a C2 flow update is published.
• Added a workaround for a rocksdb limitation where compaction cycles are not run for long periods in some use cases. Minifi now forces a compaction every 2 minutes by default.
• Fixed an issue with FilesystemRepository content repository where failed content file deletions were not properly handled. Now deletion failures are logged and retried later.
