Reduce log level of watchdog configuration failure (#3231)

Browse Source 
When in automatic mode we probably don't need to warn user about failure to set up watchdog. This is the common case and makes many users think that this feature is somehow necessary to run Patroni safely. For most users it is completely fine to run without and it makes sense to reduce their log spam.
