Log level does not support the "trace" keyword

Inizia individuando l’analisi e la configurazione del livello di log della Cloud Foundry CLI, quindi riproduci la differenza tra CF_LOG_LEVEL=debug, CF_LOG_LEVEL=trace e CF_LOG_LEVEL=6 usando cf create-package hello. Il lavoro è completato quando la parola chiave trace produce lo stesso comportamento di logging del livello numerico 6, con un test di regressione che copra l’impostazione.

Please fill out the issue checklist below and provide ALL the requested information.

• I reviewed open and closed github issues that may be related to my problem.
• I tried updating to the latest version of the CF CLI to see if it fixed my problem.
• I attempted to run the command with CF_TRACE=1 to help debug the issue.
• I am reporting a bug that others will be able to reproduce.

Describe the bug and the command you saw an issue with

While working on code changes I noticed that I wasn't able to see logs if I set the log level to trace. It turns out that the log level using the trace keyword isn't supported although it has been added to the logger 7 years ago.

What happened

Notice that a debug log is being printed when I use the debug level

$ CF_LOG_LEVEL=debug cf create-package hello
Creating and uploading bits package for app hello in org myorg / space myspace as john.doe@example.com...
DEBU[0000] convert to translatable error                 err="actionerror.ApplicationNotFoundError{GUID:\"\", Name:\"hello\"}"
App 'hello' not found.
FAILED

but that if I set the log level to trace the debug printout does not appear.

$ CF_LOG_LEVEL=trace cf create-package hello
Creating and uploading bits package for app hello in org myorg / space myspace as john.doe@example.com...
App 'hello' not found.
FAILED

however, if I set the debug level to 6, which corresponds to trace it does show:

$ CF_LOG_LEVEL=6 cf create-package hello
Creating and uploading bits package for app hello in org myorg / space myspace as john.doe@example.com...
DEBU[0000] convert to translatable error                 err="actionerror.ApplicationNotFoundError{GUID:\"\", Name:\"hello\"}"
App 'hello' not found.
FAILED

Expected behavior

I should be able to use CF_LOG_LEVEL=trace
