Bug 5346: Add odl-config-netty to odl-netconf-client

Feature odl-netconf-client applies 01-netconf.xml config file,
which expects capabilities provided by config file 00-netty.xml
from odl-config-netty feature. But odl-config-netty is not part of
odl-config-all feature, so it needs to be specified directly.

Also, added more specific capability dependency to 01-netconf.xml
and updated dependencies for netconf features pom.xml
