Add IDP v3 CAS protocol configuration GUI

[dmogn]

Mike Schwartz: There should be a config option in oxtrust JSON properties to enable CAS (because we don't want to see it in the oxTrust GUI unless its enabled...) Mike Schwartz: and it needs to be tested... Mike Schwartz: CAS is a pretty easy password protocol though.

Results of meeting with Zico:

• Yes, use memcached for CAS session sharing (localhost:11211). We also need memcached replication.
• Details of used protocol extensions will be replied later.
• We can use this 'phpCAS' to test our CAS configuration for v3 https://wiki.jasig.org/display/casc/phpcas

We can try to comment out configuration block in our CAS config to avoid using memcached. A result we don't need to start/install memcached in CE. If someone need memcached he can install memcached package and uncomment these lines.

CAS-enabling in IDPv3 requires server-side session storage. In-memory server-side storing could be an issue with memory limits.

If we enable CAS protocol in IDPv3, than we should go to memcached using as server-side session storage.

Where in this GUI it's possible to enable/disable CAS?
