support more nodes than there are AZs defined

[gusse]

what

• Allows not defining availability_zones
• Can create more nodes than you have defined AZs (once AWS provider is fixed https://github.com/hashicorp/terraform-provider-aws/issues/14070#issuecomment-771079450)

why

• availability_zones parameter shouldn't be required.
• You might want to define the AZs you use and have more nodes than AZs, e.g. use two AZs and 4 nodes

• Similar fix was done to memcached module https://github.com/cloudposse/terraform-aws-elasticache-memcached/pull/28
