Sysinit startup not possible

Atm flume isn't ready to start via sysinit, because its need a agent definition at startup:
bin/flume-ng agent -n NAME -f conf/flume-conf.properties.template

which reflect the name.foo in the config files. An easy improvement could be to improve the Node name check from missing node name into all node names.

Tech:
====
bin/flume-ng agent -f conf/flume-conf.properties.template
java.lang.IllegalStateException: Node name not specified in node.Application (Application.java):

Code:
Preconditions.checkState(configurationFile != null,
"Configuration file not specified");
Preconditions.checkState(nodeName != null, "Node name not specified");

Here flume nodeManager could iterate over all name.foo and start all flows. If one or more fails, throw an exception and go to the next available.
