Fixes #8430 - Add option forcing apipie cache reload

Trigger the reload of the cache either from cli with `-r`, `--reload-cache`  or from cli_config.yml with `:reload_cache: true`
The cache removal is indicated in the logs, look for  `Apipie cache was cleared`


I think it would be better to skip `HammerCLI::Settings.load` in this test and use `cmd.run(['-r'])`
