I am out of country now with very poor internet connectivity, so won't be able

Really appreciate your comments
I definitely agree with majority of the comments you made. Especially with how
much code it takes to add a single method to rmadmin command - may be we missed
something, but it is really too much.
regarding wrapper on top of LabelManager to behave as a service - in realy life
situation service is instantiated once per process - which is exactly what we
need, as it is really a singleton, but since UnitTests create service per unit
test it created issues with Service States in this case.
About waiting for 6 secs between tests - allowing labels ile to reload - can be
reduced further.
> Allow for (admin) labels on nodes and resource-requests

> It will be useful for admins to specify labels for nodes. Examples of labels
> are OS, processor architecture etc.
> We should expose these labels and allow applications to specify labels on
> resource-requests.
> Obviously we need to support admin operations on adding/removing node labels.
