[FEATURE] Add member management for projects

[wtschreiter]

In Rancher it all clusters and projects have a section of members.

This section allows to manage users and groups and their role binding.

In a standard rancher setup there are three predefined role bindings:

• project-owner
• project-member
• read-only

You can manage more specific rights by using a custom setting of rights.
