[API] Support new GALERA protocol in the API

Browse Source 
When a Galera load balancer is requested, we validate the
node definitions in the API rather than rely on the worker
for validation. Make sure that number of primary nodes is
one, no more and no less.

When using POST to add nodes, we check that a primary node
is not being added. We assume a primary is already defined
since the LB cannot exist without a primary.

DELETE is checked to make sure that the primary node is not
being removed.

Set the default port for GALERA protocol to 3306.
