Get contract hashes from NNS during setup

[roman-khimov]

We have a number of contracts and they use each other for various purposes, so many of them have _deploy parameters to specify hashes of other contracts. These parameters are not very useful and making deployment/upgrades more complicated then they need to be since we always have NNS in sidechain and it always has proper hashes of the target contracts.

I'm a bit confused of next deployment parameters:

• Container contract depends on Netmap contract address

  neofs-contract/container/container_contract.go

  Line 146 in 715425a

  addrNetmap interop.Hash160

• Netmap contract depends on Container contract address

  neofs-contract/netmap/netmap_contract.go

  Line 99 in 715425a

  addrContainer interop.Hash160

Will there be a conflict during deployment, or it is assumed that the hashes are known in advance (in the current topic - registered in the NNS)?

The first one is only used during cleanup and can be reworked to not do so, #327.
