19151: SAIL-298: Implemented subsystem changes.
- We didn't remove the cifs.serverName property because it is independent of host/port/context/protocol.
Applied following corrections
- Removed the email 'chain'. OutboundSMTP and InboundSMTP are separate subsystems and don't need to be chained
- Added the ability for multiple Spring-initialized subsystems to share the same category
- No need to expose mailService outside of the OutboundSMTP subsystem as far as I can tell
- GlobalDeskTopActionConfigBean doesn't need dependencies and no longer exposes the webpath property
- Fixed construction of contexts in ContentDiskDriver.
