NIFI-1274 Cleaned up TODO statements. (+3 squashed commits)
Squashed commits:
[fd101cd] Removed logic to check for presence of services to determine if token support is enabled when username/password authentication is enabled (Kerberos also requires tokens).
[c2ce29f] Reverted import changes to RulesResource.java.
[c269d72] Added Kerberos authentication mechanism.
Moved Kerberos service wiring from XML to Java to handle scenario where admin has not configured Kerberos (previously threw NullPointerException in FileSystemResource constructor). (+15 squashed commits)
Squashed commits:
[09fc694] Added Kerberos documentation to Admin Guide.
[ecfb864] Cleaned up unused logic.
[157efb3] Added logic to determine if client certificates are required for REST API (login, anonymous, and Kerberos service authentication all disabled).

Added logic to handle ticket validation failure in AccessResource.
Changed wiring of Kerberos service beans to XML in nifi-web-security-context.xml for consistency.
[c31ae3d] Kerberos SPNEGO works without additional filter (new entry endpoint accepts Kerberos ticket in Authorization header and returns JWT so the rest of the application functions the same as LDAP).
[98460e7] Added check to only instantiate beans when Kerberos enabled to allow access control integration tests to pass.
[6ed0724] Renamed Kerberos discovery method to be explicit about service vs. credential login.

[0605ba8] Added working configuration files to test/resources in kerberos module to document necessary config. This version requires the user to enter their Kerberos username (without realm) and password into the NiFi login screen and will authenticate them against the running KDC.
Also includes a sample keystore and root CA public key for configuring a secure instance.
[49236c8] Added kerberos module dependencies to nifi/pom.xml and nifi-assembly/pom.xml.
Added default properties to login-identity-providers.xml.
