This commit renames IndexLifecycleManager to SecurityIndexManager as it
is not actually a general purpose class, but specific to security. It
also removes indirection in code calling the lifecycle service, instead
calling the security index manager directly.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
