Mount Propagation

The mount namespace created by RootlessKit has rprivate propagation by default.

Starting with v0.9.0, the propagation can be set to rslave by specifying --propagation=rslave.

The propagation can be also set to rshared, but known not to work with --copy-up.

Note that rslave and rshared do not work as expected when the host root filesystem isn't mounted with "shared". (Use findmnt -n -l -o propagation / to inspect the current mount flag.)
