VStorage: make logging path configurable

Logging path can now be configured in shares config file.
When it's not set, the default logging path is appended
to mount options.

Also default logging path is changed because of:
When VStorage package is installed, default logging
path /var/log/vstorage is created. So this should
be a default value for logging path. Otherwise
user is forced to create logging path manually,
because share mount will fail.

Logging path can now be configured for vzstorage driver in
shares config file (specified by vzstorage_shares_config option).
To set custom logging path add `'-l', '<path_to_log_file>'` to
mount options array. Otherwise default logging path
`/var/log/vstorage/<cluster_name>/cinder.log.gz` will be used.
