need Vector getSpacePermissions(String token, String spaceKey) remote API method

There is currently no way to get the permissions of a given space in the remote API.

There is a method to get the permissions of a specific user on a given space, but there is no analogous method to do for a given space what "Vector getPagePermissions(String token, String pageId)" does for a given page.

The fact that the remote API doesn't provide this information is preventing me to implement security correctly in the integration work that I am doing. It is a blocker, because security is mandatory.
