Description

steps to reproduce :

1- create a cluster with 3 nodes
2- shut down membase on one of the nodes
3- create a new cluster with 3 nodes and reuse the public IP of one of the nodes
4- now you will see that ns_server from the old cluster now is trying to reset the vbuckets on the new cluster

ns_server should use the otpCookie authentication when running _set_vbucket_state command against memcached (alk: see my comment below)

we cannot use otp cookie authentication against memcached.

Previously it was discussed that we should generate unique admin user and/or password for memcached.

Looks like it's time.

I think it should just be a unique cluster ID and configuration clock. We probably already have one? This would just be an additional credential required when trying to do vbucket type managing operations.

Current cbcollect_info hardcodes this.

I think we'll need to rewrite collect info in erlang to fix this and other issues where config is either not consulted at all or is consulted somewhat kludgy.
