Revision 1868628

Improved: Avoid unecessary breakage in ‘ContainerConfig’
(OFBIZ-11256)

This restores ‘public’ modifiers on fields and move the ‘Property’
inner class back to ‘Configuration’ to avoid breakage of client code
extending the ‘Container’ interface.

In order to smooth the transition towards using getters instead of
direct field accesss, the public modifiers on fields are now marked as
deprecated.
