* lldp - use get_bin_path to locate the lldpctl executable
* This prevents failed executions
FAILED! => {"changed": false, "cmd": "lldpctl -f keyvalue",
"msg": "[Errno 2] No such file or directory", "rc": 2}
on hosts (servers and switches) with lldpd installed and running.
* Update changelogs/fragments/lldp-use-get_bin_path-to-locate-the-lldpctl-executable.yaml
Specify pull request id and minor formatting tweaks
