BUG-7527: provide Karaf 4 features

Some oddities in this patch:
* aaa-shiro pulls in commons-beanutils, which has an optional
  dependency on commons-collections; this doesn't cause any problems
  with Karaf 3, but fails on Karaf 4 (so I've added an explicit
  dependency on commons-collections)
* aaa-idmlight's "provided" jetty-servlets causes containing features
  to fail to load, so I've added a dependency on Karaf's jetty feature

aaa-cli is duplicated as aaa-cli4 for Karaf 4, otherwise we end up
with a failure loading odl-aaa-cli since the bundle has a strong
dependency on Karaf 3. This is temporary, we'll remove aaa-cli4 once
the Karaf 4 migration is done.
