OC 9450 - Auto generate chef node name when not input by user

No description provided.

The prefix 'os' was used to indicate 'OpenStack'. I wonder if we could make this show a prefix based on the provider? We could change the signature of

def get_node_name(chef_node_name)
to
def get_node_name(chef_node_name, prefix)
so nodes could get names like 'ec2-124326243' or 'hp-434283423' or 'rs-323423423'

@adamedx @mattray - Apart from defaults it might be useful to give ability for user to specify the prefix, example user may want to create 5 instances/nodes for ec2-db-server-* and 5 for ec2-app-server-* etc...?

There's already support for using -N to name the nodes, I'm not sure we need to worry about multi-node naming here. This is just about automatically providing a unique name with a prefix identifying the provider.

FWIW, spiceweasel does multi-node provisioning with an iterator.

[adamedx]

Can we add an additional spec that generates two names (or more) and validates that they are unique?

Added rspec test to test uniqueness of auto genrated chef_node_names.
Thanks.
