[org.jenkins-ci.plugins:ansible] Missing permission checks in Jenkins Ansible Plugin allow enumerating credentials IDs

Ansible Plugin 1.0 and earlier does not perform permission checks in methods implementing form validation.

This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.

An enumeration of credentials IDs in Ansible Plugin 1.1 requires the appropriate permissions.
