New podman::secret to create or delete secrets

[traylenator]

Can set secrets from:

• parameters in puppet
• loading from a file on disk
• a deferred function call.

When flag values are changed the secret will be updated. To update a changing secret it best to store a secret version as a label.

Setting a secret from puppet:

podman::secret{'foo':
   secret => Sensitive('topsecret'),
   flags => {
     label => ['version=20230615'],
   },
}

Setting a secret from a file path

podman::secret{'foo':
   path          => '/tmp/secretstuff',
   subscribe => File['/tmp/secretstuff'],
}

Setting a secret from a deferred function

podman::secret{'foo':
   secret => Sensitive(Deferred('fetch_secret',['key'])),
   flags => {
     label => ['version=20230615'],
   },
}

• Fixes: #41

In draft while I think of way to update secrets - comments very much welcome.

Add a secret version in the label works well.
