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.

Pierre Souchay a5f6ac0df4 [BUGFIX] When a node level check is removed, ensure all services of node are notified
Bugfix for https://github.com/hashicorp/consul/pull/3899

When a node level check is removed (example: maintenance),
some watchers on services might have to recompute their state.

If those nodes are performing blocking queries, they have to be notified.
While their state was updated when node-level state did change or was added
this was not the case when the check was removed. This fixes it.

Pierre Souchay 4c188c1d08 Services Indexes modified per service instead of using a global Index
This patch improves the watches for services on large cluster:
each service has now its own index, such watches on a specific service
are not modified by changes in the global catalog.

It should improve a lot the performance of tools such as consul-template
or libraries performing watches on very large clusters with many
services/watches.
