This adds a new cluster command: ipfs-cluster-follow.
This command allows initializing and running follower peers as configured by a
remote-source configuration. The command can list configured peers
and obtain information for each of them.
Peers are launched with the rest API listening on a local unix socket. The
command can be run to list the items in the cluster pinset using this
endpoint. Alternatively, if no socket is present, the peer will be assumed to
be offline and the pin list will be directly read from the datastore.
Cluster peers launched with this command (and their configurations) are
compatible with ipfs-cluster-ctl and ipfs-cluster-service. We purposely do not
support most configuration options here. Using ipfs-cluster-ctl or launching
the peers using ipfs-cluster-service is always an option when the usecase
deviates from that supported by ipfs-cluster-follow.
Examples:
$ ipfs-cluster-follow -> list configured peers
$ ipfs-cluster-follow --help
$ ipfs-cluster-follow <clusterName> init <url>
$ ipfs-cluster-follow <clusterName> info
$ ipfs-cluster-follow <clusterName> run
$ ipfs-cluster-follow <clusterName> list
