Constantinople fork for Telsius

[marcosio]

Description

As we describe in the Increase the size of the smart contract deployment issue, in business environments, the deployed size of smart contracts may exceed the 24 Kb.

If we can activate the Constantinople fork, the network will be compatible with the latest versions of the EVM/solc/solidity, the final binary code of the smart contracts will be less than the current binary generated with Byzantium version, etc.

Proposed solution:

As it is described in How to setup Constantinople fork for private Ethereum chain, we need to change the genesis file with the block in which it's activated the hard fork and the needed changes to increase the size of the smart contracts.

We need to take into account that all the validators and boot nodes must be configured with the hard fork when the network reaches the Constantinople block.

And perform the test to be sure that the network will continue working properly if it mixes the nodes with the hard fork and without it.
