[3.2] Backport separate logging for state history plugin

[ndcgundlach]

Add separate logging for state history plugin.

To enable/configure SHiP logging, add a "state_history" entry in the logging.json under the loggers section in the form:

{
    "name": "state_history",
    "level": "info",
    "enabled": true,
    "additivity": false,
    "appenders": [
      "stderr",
      "net"
      ]
  }

See the nodeos logging config documentation for more detailed info on the particular options.

Should add this logger to the example logging.json in programs/nodeos.
Also update the PR description with information about how to enable this logging in SHiP.
