ONOS-1328 Converted ONOS features to apps.

ONOS_FEATURES env. var is now deprecated!

Cells are expected to use ONOS_APPS env. var to tailor which builtin apps should be activated by default.  All builtin apps are installed by default, but can be uninstalled if desired.

Cleaned up cell definitions accordingly.
