Leave only compute pinning

It was found that if control plane was upgraded with some different
pinning options (e.g.: scheduler) except compute and pinning
wasn`t deleted while compute nodes are not yet upgraded
it leads to inability to boot instance with RPC versions error.
It was decided to leave only compute pinning.
