In this commit, we take an initial step towards converting the existing breach arbiter and utxo nursery logic into contract resolvers by moving the files as is, into the `contractcourt` pacakge. This commit is primarily move only, though we had to massage some interfaces and config names along the way to make things compile and the tests run properly.
