Introduce the ability for report owners and collaborators to control access on a per-report basis

We have a need to enable SSO for shared webapges. We want to create and share reports with internal teams that they can then bookmark in their browsers. We also embed many reports within our own internal Confluence.

Currently, within the webpage security settings we have to choose between:

• Allow anyone to access

• Allow only Aha! or single sign-on users to access

We'd like to introduce a third option that allows report owners and collaborators to control access on a per-report basis, just as we do within presentation security.
