Consul branch toINI.md

If you need to get all the keys from the branch of Consul and put in .ini file:

[service]
{{range tree "path/to/service"}}{{.Key | replaceAll "/" "." }}={{.Value}} 

1. tree get all keys by path.
2. range get access to {{.Key}} and {{.Value}} constructions.
3. {{.Key | replaceAll "/" "." }} - replace all / in path to nested keys in dir (path/to/service) to ..

For expamle,

path/to/service/key
path/to/service/dir/key
path/to/service/dir/dir/key

wil be replace to

[service]
key=foo
dir.key=bar
dir.dir.key=baz
