Add default node config

To be used by the Ubuntu 32 bit tester to reduce the ring size and allow
tests to pass on that limited memory environment. But it will take any
default node configuration you put in the rt_default_config parameter.
These are defaults: they are applied before any configuration given in
the code to *all* nodes.  Configuration passed by the test overrides it.
Example:
   { rt_default_config,
        [ {riak_core, [ {ring_creation_size, 16} ]} ] }

Fixes issue #149, related to basho/riak_core#228
If queried right after it has joined the cluster, a node may not have
the other nodes registered by the node watcher yet. Switching to waiting
until all nodes in the cluster have been registered by the node watcher
before performing query.
Also, querying for all nodes after stopping/starting just in case,
although I haven't seen problems there, but sound reasonable.
Removing assert from the call to wait_until_no_pending_changes since it
is already asserting internally.
