Class luatest.cbuilder

Usage:

local config = Builder:new()
    :add_instance('instance-001', {
        database = {
            mode = 'rw',
        },
    })
    :add_instance('instance-002', {})
    :add_instance('instance-003', {})
    :config()

By default, all instances are added to replicaset-001 in group-001,
but it's possible to select a different replicaset and/or group:

local config = Builder:new()
    :use_group('group-001')
    :use_replicaset('replicaset-001')
    :add_instance(<...>)
    :add_instance(<...>)
    :add_instance(<...>)

    :use_group('group-002')
    :use_replicaset('replicaset-002')
    :add_instance(<...>)
    :add_instance(<...>)
    :add_instance(<...>)

    :config()

The default credentials and iproto options are added to
setup replication and to allow a test to connect to the
instances.

There is a few other methods:

* :set_replicaset_option('foo.bar', value)
* :set_instance_option('instance-001', 'foo.bar', value)
