[nexus49]

Context

Currently the IDP resources are part of the core.platform-mesh.io APIExport. This APIExport is part of the default APIBindings and also visible in user (account) workspaces.

Target

• Remove the Resource from the core.platform-mesh.ioAPIExport and create a new APIExport for this resource calledsecurity.platform-mesh.io`
• Add the security.platform-mesh.io to the default API Bindings of the Orgs WorkspaceType
• Create a APIBinding in the platform-mesh-system workspace
