devlink: Add health dump {get,clear} commands

Add devlink health dump commands, in order to run an dump operation over a specific reporter. The supported operations are dump_get in order to get last saved dump (if not exist, dump now) and dump_clear to clear last saved dump. It is expected from driver's callback for diagnose command to fill it via the devlink fmsg API. Devlink will parse it and convert it to netlink nla API in order to pass it to the user.
