introduce poolOptions for legacy, p2sh and bech32 keys (#604)

* [MPOS] pass share difficulty to MySQL ++

Additionally to the changes on master we are removing the MPOS difficulty multiplier here. MPOS has been updated (currently development branch) to handle low difficulties nicely.

* add config for chaincoin

* remove redundant

* introduce poolOptions for p2sh and bech32 keys and add coin.json examples
