[ONOS-3370] Extract hostprovider and lldpprovider from openflow

There are three independent apps:
    - openflow-base
    - hostprovider
    - lldpprovider
And there is also one meta-application called openflow that
contains all three of them.

Also fix the dependency issue when the apps are loaded from disk
