This change makes Fluent Bit fail to start when a configuration includes an invalid processor (one that doesn't exist or fails to initialize). Previously, Fluent Bit would log an error but continue starting up, potentially masking configuration issues. - Add early exit conditions when a processor plugin doesn't exist - Add early exit conditions when a processor plugin fails to initialize - Improve error messages to be more descriptive Part of fluent#10305
… handling This test verifies Fluent Bit's behavior when configured with a non-existent processor. It checks that Fluent Bit properly fails to start and reports a relevant error message. Part of fluent#10305
After this change, when a plugin configuration contains an invalid property, `configure_plugins_type` returns an error which ultimately crashes fluentbit, instead of only printing an error log and continuing on. The change also fixes a small issue where `name` was printed by `flb_error` after it was freed. To properly test this change and get the test to pass with `-DSANITIZE_ADDRESS=On` on all platforms, I had to update `configure_plugins_type` to free objects that it fails to instantiate.

This backport is stale now. Once my commit is approved and merged in master I will redo this backport. I would like to wait until then to prevent any wasted effort. |

Backport #10305 and #10296.
I backported @niedbalski's change first because my change is based on it in a small way and, with the conflicts, my choices were to either:
goto errorin my change is missed since it wouldn't conflict anymore.both of which felt worse than just picking his change first.
His commits had no conflicts except that I dropped two small chunks from his change in flb_processor.c that updated log messages that do not exist in 3.2.
