Pierre Souchay 3d0a960470 When renaming a node, ensure the name is not taken by another node. 
Since DNS is case insensitive and DB as issues when similar names with different
cases are added, check for unicity based on case insensitivity.

Following another big incident we had in our cluster, we also validate
that adding/renaming a not does not conflicts with case insensitive
matches.

We had the following error once:

 - one node called: mymachine.MYDC.mydomain was shut off
 - another node (different ID) was added with name: mymachine.mydc.mydomain before
   72 hours

When restarting the consul server of domain, the consul server restarted failed
to start since it detected an issue in RAFT database because
mymachine.MYDC.mydomain and mymachine.mydc.mydomain had the same names.

Checking at registration time with case insensitivity should definitly fix
those issues and avoid Consul DB corruption.
