This makes the CLI slightly nicer to use. In particular, the new dynamic between --share and --persist means that a user may do the following:
$ bst --persist /tmp/foo true
$ bst --share user,mnt,net=/tmp/foo sh
Whereas before the change, they would have to manually specify --share-user=/tmp/foo/user --share-mnt=/tmp/foo/mnt --share-net=/tmp/foo/net.
--unshare as a counterpart of --share is also really useful for overriding a previous --share all if it is desirable to only unshare a select set of namespaces.
