Conul-template is not highly fault-tolerant to Consul failure

[iAmoric]

In documentation, it's written:

By default Consul Template is highly fault-tolerant. If Consul is unreachable or a template changes, Consul Template will happily continue running.

The observed behavior shows it's not the case. Here are the logs from Consul-template (using the default retry configuration):

Obviously, the service consul-template failed because Consul was not reachable
