Provide mechanism to see runtime details as admin

As a continuum user without access to the host environment, I would like the ability to see details about continuum's runtime environment in the web application so that troubleshooting issues is possible without getting host access.

Because some of this information may present a security risk, this ability should be protected by privileges and should not be exposed to untrusted users.

Information that is often useful during troubleshooting:

• Java version
• System properties, including os/arch
