Resolving Karaf Northbound API issues with a few related fixes

1. Upgrading Apache Tomcat Patch version from 7.0.32 to 7.0.53 (https://git.opendaylight.org/gerrit/10110)
2. No impact to the legacy distribution.
3. Fixing the Jackson - Jersey binding by fixing the Classloader confusion where multiple bundles exports javax.ws.rs
4. Adding a temporary hack for the Http authentication by adding a karaf-tomcat-security bundle
   The existing security bundle is rift with dependencies into a lot of deeply chained AD-SAL NSF and needs a lot of pruning.
   Hence in order to make progress in Karaf testing and development, Have bypassed it temporarily and we will fix it soon.
