Add foreign identity process support (MOAID-61).

- moa-id auth web.xml: Replace servlet mapping "/GetForeignID".
- Fix some javadoc of AuthenticationServer.
- Set GetForeignIDServlet deprecated.
- Remove redundant code across several classes.
- VerifyIdentityLinkTask: Separate identity link verification from subsequent (a) creation of CreateXMLSignatureRequest (ProcessIdentityLinkTask) and (b) creation of InfoBoxReadRequest (CertificateReadRequestTask).
