Node operator documentation for 0.74.0 deployment

[gordsport]

Feature overview

In order to ensure that the validators carry out the IPFS and block explorer migrations, machine specifications (related to the OOM/Disk space issues seen) and the EVM chain data sourcing correctly
We will create easy to use node operator
So that the node operators can easily migrate from 0.73.x to 0.74.0

Tasks

A checklist of the tasks that are needed to fully document the requested topic.

• Document IPFS migrations (both for operators using and NOT using Visor)
• Document Block Explorer migrations
• Document any EVM data sourcing config that is required (Gnosis/Arbitrum event providers)
• Review the validator node hardware specifications
• Review the data node hardware specifications
• Any other 0.74.0 instructions
  • Data node
  • Core
  • Tendermint upgrade to 0.38
