Configures the specified VPC endpoint as restriction for the project,
or updates the existing restriction. When a VPC endpoint is assigned
as a restriction, only connections from this specific VPC are accepted.
Note that a VPC endpoint can only used as a restriction on a project
after it has been assigned to the parent organization.
This endpoint is under active development and its semantics may change in the future.
