With the advent of Clique, some JSON RPCs pertaining to mining are
no longer going to produce appropriate results.
The Get/Set coinbase RPCs cannot affect a Clique based miner, as such
the miner throws an "Unsupported Operation" exception. The JSON
handler is responsible for catching this, and returning an
appropriate error code.

* [NC-1685] Fix BlockHashOperation so it handles blocks being added on forks and gets the hash of the block at the requested number on that fork rather than on the current canonical chain.
* [NC-1644] Cache block hashes across all transactions in a block.

The MiningCoordinator has been split into common, and ethhash
specific funcationality.
This adversely affects the JSON RPC, in that all mining related
RPCs are now generic based on the type of miner being used.
