Combine install/upgrade scripts, and new arguments.

[ludeeus]

• All scripts has been renamed, they are no longer prefix'd by install_ / upgrade_.

• If there was an install and upgrade script, these are now combined.

• functions in hassbian-config is updated to new structure.

• Add command line option -f to to force scripts.
  

• Add command line option -y to to accept pormts.

  • add -y option to share-log function
  • add -y option to mosquitto installer
  • add -y option to homebridge
  • add -y option to appdaemon

[ludeeus]

If user input is required, like in the duckdns script, they do not need an implementation for -y
But in scripts like mosquitto and homebridge we ca implement it by adding this for the parts that can have default values:

if [ "$ACCEPT" == "true" ]; then
  #Do this if -y is active
  mqtt_username=pi
else
  #Do this if -y is not active
  echo -n "Username: "
  read mqtt_username
fi

Looks good. Merging into dev.
