PdP policies

[oharsta]

The following requirements need design and an implementation:

• Visualize the option on an application, that all users have to use a loaX when logging in. This is a read-only option for the IdP admin / member. This setting is maintained by SURF.
• When creating a policy, the user does not have to choose: there are two buttons
• When creating a policy it must be possible to add multiple SP's and choose the negate option for this
• Put the policies menu-item in the left-side menu
• Add the SP names (can be multiple) to the overview policy card
• Mark / detect invalid IP addresses
