Add config_name parameter to define the name of the consul config

Add config_name parameter to give users the flexibility to name their config files in the name they want.

Seems fine, but can you tell me more about your use-case? Why not just have it be config.json?

[bogdankatishev]

We will be using the upstream hashicorp consul package, which includes a Consul service file, which has this line: ConditionFileNotEmpty=/etc/consul.d/consul.hcl. So we will change the Consul config name to: consul.hcl.

And because hcl is JSON-compatible, the way of working will be the same.

Hmm.
