The node identity TTL defaults to 24hr but can be altered by setting the node identity TTL parameter. In order to allow setting and viewing the value, the field is now plumbed through the CLI and HTTP API. In order to parse the HCL, a new helper package has been created which contains generic parsing and decoding functionality for dealing with HCL that contains time durations. hclsimple can be used when this functionality is not needed. In order to parse the JSON, custom marshal and unmarshal functions have been created as used in many other places. The node pool init command has been updated to include this new parameter, although commented out, so reference. The info command now includes the TTL in its output too.
