This PR is preparation for ETH only staking. We extracted some common parts of KeepBonding contract that almost entirely can be used for ETH bonding and placed them in AbstractBonding. The only difference, for now, is withdraw that in case of KEEP token staking has to support grantee roles check. This is an abstract function in AbstractBonding implemented by KeepBonding.

Refs: #271

Moved parts of the code that are common and will be used for ETH bonding
from KeepBonding to AbstractBonding contract.
Only withdraw related functions remain in KeepBonding as they require
different roles handling.

As TokenStaking contract has been refactored in keep-network/keep-core#1867
we can use Authorizations and StakeDelegatable contracts calls as these
contracts define the functions we use in bonding. In this commit we use
separately Authorizations and StakeDelegatable instead of TokenStaking
to be more flexible and able to use common code from AbstractBonding for
both KEEP token and ETH bonding.

We added abstract functions for the calls we expect to make to staking
contract. For KEEP token staking we expect calls to TokenStaking and for
ETH staking calls to dedicated staking contract. We no longer need to
pass two addresses: Authorizations and StakeDelegatable contract which
seemed to be confusing.
Updated unit tests stubs to handle functions added to AbstractBonding
contract that should implement calls to staking contract holding
informations about delgation.

@nkuba nkuba force-pushed the abstract-bonding branch 4 times, most recently from 8655894 to aa0503f Compare August 11, 2020 22:05
Solium complains about indentation problems but indentation is fine.
Indentation is verified and fixed by prettier so we can ignore
indentation cheks from oslium.

We usually do public* in other tests, can we rename it to publicWithdrawBond to keep it consistent?
