Description

• Similar to the changes made through PR: https://github.com/aerogear/charmil-plugin-example/pull/6, in the charmil-plugin-example repo.
• Replaced the RHOAS config implementation with the one used in the Charmil Core Config package (after improving it).
• Once this PR is merged, we'll have both the host and plugin config integrated (ie. instead of creating a separate file for plugin config, now the plugin config will be automatically be loaded/saved from/to the host config file).

Demo

• While using the host and plugin CLI together:

@namit-chandwani I have pushed broken service-registry commands in host. Not able to configure config package. As you have done changes the config package. Can you apply the changes in the service-registry commands, according to new config package?

Then we can merge this - in plugin I am doing the same for artifacts commands.

initial stage PR. Need to use charmil utilities for both plugin and host. But this is how I got it working.' Initialized Plugin's factory in host to pass it to plugin.
