Manage components with ConfigurationAdmin

[tcalmant]

Currently, the only ways to manage components easily in iPOPO itself are:

• let iPOPO create the component when the factory will be active (waiting list)
• use the initial configuration file (which uses a waiting list underneath)
• create the components when the factory is active (custom instantiation process)

This means we currently have no way to manage the composition after its instantiation.

An article seems to talk about the idea on the OSGi side:
