Using curl to health check to themis: [themis-server]:80/health returns this (I removed the server name):
HTTP/1.1 200 OK
Content-Length: 270
Content-Type: application/json
Date: Mon, 05 Oct 2020 19:54:15 GMT
Connection: close
{"details":{"themis":{"name":"themis","status":"ok","details":{"StartTime":"2020-09-21T17:20:29Z"},"check_time":"2020-10-05T17:20:29.088001355Z","num_failures":0,"first_failure_at":"0001-01-01T00:00:00Z"}},"server":"[themis-server],"status":"ok"}
Version should be provided in either the health check or by header as the other xmidt servers do.
