shell: dial volume servers on their registered gRPC port in volume.scrub, ec.scrub, volume.server.state (#12315)

* shell: dial scrubbed volume servers on their registered gRPC port

volume.scrub, ec.scrub and volume.server.state built each data node's
address from its HTTP address alone, so a volume server whose gRPC port
is not the HTTP port + 10000 was dialed on the wrong port.

* shell: resolve -node volume servers to their registered gRPC port

An explicit -node/-nodes list was dialed on HTTP port + 10000 too.
Match each entry against the topology and take the data node's gRPC
port; an address the master does not know is used as given.

* shell: keep a gRPC port given in -node

A node given as host:port.grpcPort was rewritten to the registered gRPC
port; only a bare host:port takes it from the topology.

* shell: dial -node volume servers when the topology is unavailable

An explicit node list did not need the master before; keep using it as
given if the volume list cannot be fetched. Selecting every node still
requires the topology.

* shell: bound the topology lookup for an explicit -node list

With the master down, volumeServer.state -nodes waited on the master
forever instead of reaching the given volume servers. Give the lookup a
30s deadline and fall back to the addresses as given.

* shell: resolve volume server addresses from a topology-only listing

Only the data nodes are needed to find each server's gRPC port, so ask
the master for the topology without its volumes and ec shards. A large
cluster no longer risks running past the -node lookup deadline and
falling back to the HTTP port + 10000.

* shell: skip the topology lookup when every -node names its gRPC port

A host:port.grpcPort entry is dialed as given, so a list made only of
those does not need the master and no longer waits on it during an
outage.
