core:  initVdsOnUp- remove reconstruct and host status.

*Host that runs through init vds on up shouldn't attempt to reconstruct.

*In case of failure during ConnectStoragePool, the host should fail in
initalizeStorage() only if the master domain isn't in inactive/
unknown status and the exception wasn't XmlRpcRunTimeException (which is
represented by VdcBllErrors.VDS_NETWORK_ERROR.
