Set up TLS for Stagnet 3 so we have HTTPS

[gordsport]

This is to set up TLS for tm.nXX.stagnet3.vega.xyz and api.nXX.stagnet3.vega.xyz URLs. nXX.stagnet3.vega.xyz already has it.

In practice we need to review the caddyfile config, and re-do it by separating:

• vega core stays under nXX.stagnet3.vega.xyz (and only vega core)
• data-node goes under api.nXX.stagnet3.vega.xyz
  • also GraphQL goes under the standard path
  • for validators, when the data-node is not running, can we somehow detect that situation and handle accordingly (so we don't have to keep separate config for validator and non-validator)
• tendermint goes under tm.nXX.stagnet3.vega.xyz

We need to update caddy config: https://github.com/vegaprotocol/networks-internal/blob/main/stagnet3/vegacapsule/jobs/node_set.tmpl.nomad#L91-L188
