Patching CLI: document and enable for tab-completion --distribution, --module-path and --bundle-path

As part of WFLY-1787 patch cli command was enhanced with --distribution, --module-path and --bundle-path arguments to specify the relevant target paths when running in the disconnected mode. The arguments though have been hidden from the TAB-completion and not mentioned in the command's help description.
They do make sense for end users in the disconnected mode, so it makes sense to make them fully available.
