Add check that ovs_extra is passed as list
This patch adds a check that ensures the ovs_extra option, if present,
is passed in as list and raises an InvalidConfigException if not.
It addresses the issue that a user may mistakingly pass the value as
string, which would cause an error later when appending the failure
mode or when formatting the ovs_extra parameter.
Note: Also fixes a sample file in which ovs_extra was passed as string.
