Spike: investigate how to make running a node as simple / user error free as possible

[gordsport]

Issue

This spike is to investigate how we can make running a node as easy as possible for node operators.

Things to consider would be:

• having init run behind the vega start command so we always initialise the config
• making the default config as easy and correct as it can be to avoid errors
• validations to check configs etc.. are valid before submitting commands / or return useful errors
• how can we make the config easier to use yet be backwards compatible
• other ideas / options

The scope of this issue is to:

• [ ] Identify areas we can make running a node as easy and user friendly as possible
• [ ] List these ideas along with the perceived effort and proposed priority for implementing
• [ ] List any key areas of risk with options
• [ ] Any other useful information

Once this investigation has been conduced we can review the outcome and scheduling in the work accordingly

A few people asked about this recently :) Some of the validator were also it is very painful to start Vega from the network history/ remote snapshot
