juju list-credentials --show-secrets does not display passwords

[Nicholas Skaggs]

juju list-credentials --show-secrets does not display password data, unless used with --format yaml.

The following commands all fail to show additonal information using --show-secrets
juju list-credentials --show-secrets
juju list-credentials --format json --show-secrets
juju list-credentials --format tabular --show-secrets

When used with --format yaml, --show-secrets works.

juju list-credentials --format yaml --show-secrets

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Anastasia (anastasia-macmood)]

This is working as designed - password data can only be seen in yaml format.
When --show-secrets is specified for all other formats, we need to inform the user to that effect:
"--show-secrets displays password data in yaml format only"

[Anastasia (anastasia-macmood)]

Actually, both json and yaml formats display secrets when asked. I'll update option and command help.
