examples: add load-test end-to-end example

[rjeczalik]

fixes #40

@rjeczalik I'm missing something: where do you define the number of type of the loader VMs?

[rjeczalik]

@tzach Here's the relevant part:

module "scylla-bench" {
	source    = "github.com/rjeczalik/terraform-aws-scylla-bench"
	username  = data.scylladbcloud_cql_auth.mycluster.username
	password  = data.scylladbcloud_cql_auth.mycluster.password
	seeds     = split(",", data.scylladbcloud_cql_auth.mycluster.seeds)
	instances = 4
	keys      = 1000000000
	limit     = 10000

	depends_on = [aws_route_table.bench]
}

By default aws_instance_type is c4.large and can be changed to anything else. Number of instances is set by instances variable.

By default aws_instance_type is c4.large

Where is this default? could not find it in the code

right there within the bench module, @tzach

is byoa_id and enable_dns needed for this example? I would keep it as simple as possible

@ilya-rarov - FYI, this one will require testing. I'll talk to you about the priority.
