ARTEMIS "ping" + health report

[vkotronis]

Is your feature request related to a problem? Please describe.
Currently we do not have a tool (script, utility, etc.) that we can invoke from an external machine to extract information
on the current status of ARTEMIS (module health, etc.).

Describe the solution you'd like
Develop script that uses secure communication to connect to ARTEMIS and get info on:

• module health (on/off)
• update/hijack statistics
• current ARTEMIS state (uptime, etc.)
• docker microservices that are up/down
• other useful information

This script could run periodically and for several ARTEMIS instances (IPs, ports and credentials should be supplied
as input to the script).

Describe alternatives you've considered
"ping"-like tool, connect via the UI-used ports (HTTPS - 443)
