+ Deploy openstack with juju, including manila and manila dashboard. Create a share and attempt to list shares via the manila dashboard. This should be successful.

+ [Regression Potential]
+ I don't see any potential regression. The manila dashboard can't list shares so this will fix that regression. The fix is limited to the share_list() function.
