Jenkins WSO2 Oauth Plugin does not mask the WSO2 Oauth client secret on the global configuration form

Jenkins WSO2 Oauth Plugin 1.0 and earlier stores the WSO2 Oauth client secret unencrypted in the global config.xml file on the Jenkins controller as part of its configuration.

This client secret can be viewed by users with access to the Jenkins controller file system.

Additionally, the global configuration form does not mask the WSO2 Oauth client secret, increasing the potential for attackers to observe and capture it.
