Better error handling and health check

[LostAndDead]

Adds better error handling for when a connection to a Chibisafe server cant be made

• Every fetch is now in a try statement
• If any request fails the main loop is paused
• Will automatically check/try to resume the connection every 15 seconds
• Disabling the loop via commands is not separate from the error pausing
• Docker health check script has been added, and will flag unhealthy if a connection cant be made

Going to let it run for a bit and do a bit more testing, but i think its good to go.
