added "availability" section in HA Discovery

Browse Source 
This will allow to not remove discovery topics during each ems-esp restart (MQTT init), so it can solve issue #910.

After applying this fix (and removing from the code commands that delete discovery topics) HA no longer reports errors/warnings in the log. I'm testing if for over a week.
Now it is enough to delete discovery topics only when it is really needed (e.g. the entity has been removed by customization, discovery prefix has been changed or the HA option has been disabled in the configuration).
