Fix tomoscan crawler slowness in devnet and testnet

[etienne-napoleone]

Seems like tomoscan crawler is slow and hard to catch up with the chain in testnet and devnet as the chain is accessed through WAN. To fix it, we need to implement local access on those envs:

• [x] Testnet: access blockchain locally on a masternode
• [x] Devnet: deploy fullnode connected to testnet
• [x] Devnet: access blockchain locally on testnet fullnode
