Till now the run() method in vstart_runner.py accepts commands only as
a (Python) list. It is very inconvenient to write commands as
['setfacl', '-m', 'user:someuser:rwx', 'somedir/somefile'] when they
can be simply be written as
'setfacl -m user:someuser:rwx somedir/somefile'. Also, converting the
latter form to former one is exceedingly simple. So writing commands as
strings should be allowed.
