This is a client tool to the systemd-imdsd@.service added in the previous commit. It's mostly just a 1:1 IPC client via Varlink. It can be used to query any IMDS key, but it's primary usecase is to acquire the "userdata" from IMDS. Moreover, if invoked with the --import switch it will check if the userdata contains a list of system credentials. If so, it will import them into the local credstore. If the userdata does not look like a list of system credentials no operation is executed, under the assumption the data is intended for cloud-init instead. It also imports a couple of other fields, if available and recogniuzed, such as SSH keys and the hostname.
