returned by it, that information can be retrieved by other opcodes).

Also, remove the node/instance list from "gnt-cluster info" as it
doesn't make sense to duplicate this information.

Reason: if left ConfigWriter, nodes don't know to which cluster they belong.
This will bite us later when we'll revisit node join operation.

Cons: we lose the cluster name from the config file, which means a
standalone "cluster.data" is a little bit harder to analyze. But I have
a plan for this which will follow shortly.

Implementing this will also allow us to cleanly fix "gnt-cluster
getmaster".

cluster object.

Also let's move the tcpudp_port_pool to the cluster object.

This also means we can get rid of a lot of infrastructure too:
  - the master/node config files checkers
  - one rpc function

- Split up info tests and add more of them
- Replace map() by [x for x in y]

  - move the master node name from the ConfigWriter to SimpleStore (all
    nodes need this, and it was the only thing pulled in from the
    ConfigWriter on nodes)
  - fix mcpu.py and the testing w.r.t. this change; for testing, rename
    the fake_config.py to mocks.py and add a FakeSStore object
  - then add a ganeti-master script which can be run on any node at boot
    and which will not do anything if not master on start (on stop it
    will still try to remove the ip address)
  - also add a new cluster-wide variable (master_netdev) that determines
    on which interface we add this ip address; it's customizable at
    cluster init time
  - also remove the cluster name file which was separately handled from
    ssconf (not needed anymore)
  - remove the master init.d links from the list of config files as this
