feat(comms): add support for the Grafana/Loki log engine

recognizes the grafana engine manager type, also reduces arrays of
log fields down into single objects:

the elastic & log analytics (LA) engines return rows formatted like:
{
  lines: [{
    fields: [
      { timestamp: "...", container: "...", ...},
    ]
  }]
}

and the loki engine currently returns rows formatted like:
(separate objects per field)
{
  lines: [{
    fields: [
      { tsNs: "..." },
      { pod: "..."},
      { log: "..." }
    ]
  }]
}

so just forcing the loki engine results to look like the elastic & LA
